Questions and answers
Every question gabbaim ask, answered with real cases
From the first Shacharit to Selichot after midnight: how to enter each kind of schedule so the board, the lobby screen, the printed luach and the Shabbat email stay right all year.
Getting started
What is shul.info?
A schedule board for your shul. You enter each minyan and shiur once, as a rule ("Mincha 15 minutes before sunset", "Shacharit 06:30 on weekdays"), and shul.info works out the right time for every day of the year.
The same schedule then feeds your public board at <your-shul>.shul.info, the lobby screen, the printed luach, the weekly email and the WhatsApp message. You change it in one place and every copy follows.
How does the free trial work?
How long does setup take?
Can I upload our printed luach instead of typing it?Full plan
Yes. Upload a photo, scan or PDF of the luach in the setup wizard or in the assistant. It reads the rows and lays them out as proposed schedule items that you check one by one.
Nothing is saved until you confirm. Rows it could not complete (a missing day, an unclear time) stay on the card with what is missing, so you can answer and save them.
Which plan is right for us?
Free: the board, the schedule with every timing rule, zmanim, announcements, content pages and a lobby screen. Many small shuls need nothing more.
Screen (in Israel): adds vice gabbaim, e-paper boards, undo and backups, memorials and sponsors, and app alerts.
Full: adds the printed luach and PDFs, the weekly email to subscribers, the assistant, and your own web address.
Each answer on this page shows a badge when it needs a paid plan.

Times that move with the sun
What is the difference between a fixed and a dynamic time?
A fixed time is a clock time: Shacharit at 06:30. It stays the same every day.
A dynamic time follows a zman: Mincha 15 minutes before sunset. It is calculated fresh for every date from your shul's location, so it moves with the seasons by itself. The board shows the day's time in large digits and the rule in small letters, so people understand why it changed.
Example
Mincha = sunset −15. In Jerusalem that is about 19:37 at the end of June and about 16:29 in December. You never touch it.
Which zmanim can a time follow?
Alos hashachar, sunrise, sof zman Shma (Magen Avraham and GRA), sof zman tefilla, chatzos, mincha gedola, plag hamincha, candle lighting, sunset, tzais hakochavim, Rabbeinu Tam and chatzos halayla.
The offset can be up to five hours before or after the zman. Each zman is calculated by the opinions you chose for your shul (see "Whose zmanim do you use?").
Can a sun-based time be rounded to a round number?
Yes. A dynamic time can be rounded to every 5, 10 or 15 minutes (or any interval up to 60), upwards, downwards or to the nearest. Many shuls round towards the stricter side: Mincha before sunset rounds down, Maariv after tzais rounds up.
Example
Maariv = tzais +0, rounded up to 5 minutes. Tzais at 19:52 shows Maariv 19:55; tzais at 19:55 stays 19:55.
Can a dynamic time have limits, like "never after 08:30"?
Yes. A dynamic time can carry an earliest and a latest clock time. The calculated time is clamped into that window, and the limit always wins over rounding.
Example
A shiur before Shacharit = sunrise −20, latest 06:00. In summer it follows the sun; in winter, when sunrise −20 would be 06:15, it stays at 06:00.
Can a time change only once a week instead of every day?
Yes. A dynamic time can hold one time for the whole week (Sunday to Shabbat), so congregants are not chasing a minute every day. You choose which time it holds: the earliest of the week, the latest of the week, or the time of one weekday you pick.
Rounding and earliest/latest limits still apply after the hold.
Example
Mincha = sunset −15, hold the week's earliest. All week the board shows the time that is still early enough on the day sunset is earliest.
Can one minyan be timed from another, like "Maariv right after Mincha"?
Yes. Choose "relative" timing and pick the row it follows. It can start a number of minutes after the other row ends (using that prayer's length) or after it starts.
The board shows such a time with a ~ in front, because it is an estimate: the real end depends on the minyan.
Example
Mincha = sunset −20 (lasting 15 minutes). Maariv = relative, at the end of Mincha +0. If Mincha is 18:40, Maariv shows ~18:55.
How many minutes before sunset is candle lighting?
The zmanim card shows seconds. Which time does a rule count from?
From the zman exactly as the card shows it. If you chose to display seconds rounded to the minute, a rule counts from that rounded minute, so what the congregant sees and what the rule computes always agree.
Example
Sunset is 16:55:56 and the card shows 16:56. Candle lighting "25 minutes before" is 16:31, not 16:30.
The complicated schedules
We have a minyan every 15 minutes all afternoon. Do I need thirty rows?
No. One row can repeat. Give it a first time and a step (every 5 to 240 minutes), and an end: either a clock time or a zman. It stays one row everywhere: one thing to edit, pause or move.
The board shows the range and the step. The "next minyan" countdown counts to the next one in the series. The printed luach shows the range in the cell. A clock end earlier than the start is read as after midnight, so a Maariv series can run past 00:00.
Example
Mincha from mincha gedola, every 15 minutes, until sunset. In Jerusalem at the end of June the board shows "13:16–19:46 · every 15 min": the last minyan that still starts before the 19:52 sunset.
Where to set it
- Schedules → the row → Repeat (collapsed section of the form)
In bein hazmanim we daven later. How do I set that up?
With two rows and one period. Create a period called "Bein hazmanim" (there is a ready-made preset for each break). On the everyday Shacharit, tick that period under "Pause during". Then create a second Shacharit at the bein hazmanim time and tick the same period under "Runs only during".
Each year the period's dates are worked out again, so you never retype them. The admin list marks the seasonal row with the period's name.
Example
Shacharit 06:30 (paused during Bein hazmanim Av) and Shacharit 08:00 (runs only during Bein hazmanim Av). From 10 Av to the end of Av the board shows only 08:00.
Where to set it
- Periods → Add period → pick a preset
- Schedules → each row → periods
What is a period, and which kinds are there?
A period is a stretch of days you name once and reuse: rows can pause during it, or run only during it. Change the period, and every row that uses it follows.
A period can be built from: plain dates; a Hebrew-date range that repeats every year (Adar becomes Adar II in a leap year by itself); a holiday with days before and after; the Selichot season by rite; summer or winter clock time; Behab; Rosh Chodesh; Yom Kippur Katan; Shabbat Mevarchim, Shabbat Shuva, Shabbat HaGadol or Taanit Bechorot; Shovavim; and the nights of Kiddush Levana.
Presets cover the common ones, so most gabbaim pick from a list rather than typing dates. The period list shows the next time each one falls, with the Hebrew date under the civil one.
How do I add Selichot that start on the right night every year?
Use a Selichot period, choosing the rite. Edot HaMizrach starts on Rosh Chodesh Elul. Ashkenaz (and Nusach Sefard, which follows the Ashkenazi rule) starts on Motzaei Shabbat at least four days before Rosh Hashana, which is the rule no simple date range can state: when Rosh Hashana falls on Monday or Tuesday, it starts a week earlier.
Both run until Erev Yom Kippur, with Rosh Hashana itself carved out automatically. Shabbat is not carved out: untick Shabbat on the row's days of the week.
Then make the Selichot row "Runs only during" that period.
Example
Ashkenaz, Elul 5787: the first Selichot is Motzaei Shabbat, 25 September 2027 (filed under Sunday the 26th, see the next question), and the last on Erev Yom Kippur, 10 October.
Our Selichot is after midnight. Which day does it belong to?
A fixed time such as 00:30 is simply on the day it falls on: the Motzaei Shabbat Selichot at 00:30 are a Sunday row.
A time that follows a zman can cross midnight by itself: chatzos halayla, or a late time that an offset or a shift pushes past 00:00. Such a row is entered on the evening it belongs to and said on the next calendar day, and shul.info handles both: dates you typed yourself (a pause you set from the board for "today") are read on the day it is scheduled, the one in front of you. Dates the calendar computes (the Selichot season, a holiday, a Hebrew-date range) are read on the day it is actually said.
That is why Selichot at chatzos on Motzaei Rosh Hashana count as those of Tzom Gedalia, and why a Motzaei Shabbat row entered on Saturday falls inside the Selichot season. The printed luach marks such rows "after midnight" and sorts them last.
Example
In Jerusalem, a row at chatzos halayla is about 00:35 in Elul (summer time) and about 23:30 in Kislev. It follows the clock: in Elul it belongs to the next calendar day, in Kislev to the same one.
Our times change when the clocks change. Can that be automatic?
Yes. A period can be "summer time" or "winter time", in your shul's own time zone. The change dates come from the official time-zone database, so an Israeli shul follows Israel's rule and a shul in New York follows America's.
The day of the change belongs to the season its noon is in. A minyan that only exists in winter runs only during "winter time"; its summer counterpart pauses during it.
Example
Shacharit 06:15 runs only during winter time, Shacharit 05:45 runs only during summer time. On the night the clocks move, the board switches by itself.
On Rosh Chodesh Shacharit starts 15 minutes earlier. Do I need another row?
No. A row can carry its own shift per type of day: fast day, Rosh Chodesh, Chanukah and Chol HaMoed, each earlier or later by your minutes, with an optional note. The board shows a small chip on the shifted row.
Shifts never add up. When a day is two types at once, only one applies, in the order fast day, Rosh Chodesh, Chanukah, Chol HaMoed. On a dynamic row the shift is applied before rounding and limits, so "never after 08:30" still holds.
Example
Shacharit 06:30, Rosh Chodesh −15, Chanukah −10. Rosh Chodesh Tevet 5787 (10–11 December 2026) is also Chanukah: Shacharit is 06:15, from the Rosh Chodesh shift alone.
Where to set it
- Schedules → the row → Day-type shifts
Can a row appear on Yom Kippur Katan, Shabbat Mevarchim or Kiddush Levana only?
Yes. Each has its own period type, computed from the calendar every month: Rosh Chodesh (both days when there are two, never Rosh Hashana), Yom Kippur Katan (the day before Rosh Chodesh, brought back to Thursday from Friday or Shabbat, and skipped where it is not said), Shabbat Mevarchim, and the nights of Kiddush Levana (from the 3rd or the 7th until the 15th).
Make the row "Runs only during" the period and it appears on those days alone.
Example
A Yom Kippur Katan Mincha with Selichot in 5787 appears on 9 November 2026, then skips Tevet (Chanukah) and appears again on 7 January 2027.
What about Behab and Shovavim?
Both are period types. Behab is the Monday, Thursday and Monday after the first Shabbat following Rosh Chodesh Cheshvan or Iyar (if Rosh Chodesh is on Shabbat, it waits a week). Shovavim runs from the Sunday after parashat Vayechi to Shabbat Mishpatim, or Tetzave in a leap year, unless you choose six weeks.
Use them for Selichot, a Mincha with Avinu Malkeinu or extra shiurim.
Example
Behab Cheshvan 5787: Monday 19, Thursday 22 and Monday 26 October 2026.
Our Mincha is 17:00 in summer, but in winter sunset comes first. Can it disappear by itself?
Yes, with a zman condition. A fixed row can be told: show only while my time is at least N minutes before (or after) a zman. On days the condition fails, the row is simply not on the board, the luach or the email.
Pair it with a second, dynamic row for the rest of the year ("sunset −15" shown only when the 17:00 row is not), and the board always shows exactly one Mincha.
Example
Mincha 17:00, condition: at least 20 minutes before sunset. While sunset is 17:20 or later, 17:00 shows. From the day sunset is 17:19, it disappears.
Where to set it
- Schedules → the row → Show only while… (zman conditions)
Can a shiur be held only inside a window between two zmanim?
Yes. A row can carry several conditions, and all must hold. A condition can also be a ceiling ("at most N minutes") instead of a floor ("at least N minutes").
Example
A shiur at 18:00, shown only while it is at least 105 minutes before sunset and after plag hamincha. Another example: Maariv at 21:00 only while it is at most 125 minutes after sunset.
Can a dynamic row have a condition too?
A minyan says Selichot and then Shacharit. Can they appear together?
Yes. Group the rows and give the group a name. The board shows one card headed by the name with a line per prayer. On the printed luach the group gets its own band.
Each line still behaves like a full row: you can edit or pause it on its own. If only one member happens to be on the board that day, it shows as a plain row.
Example
"Minyan Alef": Selichot 05:40, Shacharit 06:15. "Minyan Bet": Selichot 06:30, Shacharit 07:00. Two cards instead of four mixed rows.
Today only, Mincha is half an hour later. How do I change just today?
On the website: open the board, turn on edit mode, pause the row for today, and add a one-off row for today's date ("special day") at the new time. Tomorrow the regular row is back by itself.
On an e-paper wall board, a gabbai with a PIN can shift today's time or add today's note directly. The row shows "changed today" or your note. Such a one-day change also appears in the row's form on the website, where you can clear it.
Should I pause a row or delete it?
Pause when it will come back: no minyan this week, a shiur on summer break. Set the dates, or tick a period. The row disappears for those dates and returns by itself.
Delete when it is gone for good. A row that ended can also simply carry an end date.
From the board in edit mode, "show hidden" lists today's paused rows, each with the reason, and a Resume button for a real pause.
How do I enter the schedule for Pesach or Rosh Hashana?
Add rows with "Applies to: Holiday" and pick the holiday. Its dates fill in by themselves (the Israel or diaspora calendar, according to your location). Each row can be a fixed or dynamic time, like any other.
For a day the regular weekday minyan does not run, pause it for that day. The holiday-preparation check (below) finds the ones you forgot.
Rosh Hashana falls on Shabbat. Will the shofar row disappear?
Yes, when the row is tagged as shofar. A tagged shofar, lulav or tashlich row is not shown on a day it is not done: shofar and lulav not on Shabbat, and tashlich moved to its day when the first day is Shabbat.
The holiday check flags a shofar row with no tag on a Shabbat, so you can tag it with one click.
Do I have to enter every holiday again next year?
Is there a check before each chag?
Yes. About 30 days before a chag, the Schedules tab shows a preparation card. It has three steps:
Roll: bring last year's rows forward if you have fewer this year. Times: for times still carried over from last year, it suggests this year's time at the same distance from sunset, tzais or candle lighting, rounded away from the zman. Check: it looks for a shofar row with no tag on Shabbat, a weekday minyan still showing on Yom Tov, Maariv or candle lighting before tzais on the night of a second day, the Elul shofar still showing on Erev Rosh Hashana, and room clashes. Each finding has a one-click fix.
On the printed luach, why is Friday's Maariv at the top of Shabbat's page?
Because the day begins at night. The Maariv that opens Shabbat or a chag is printed at the top of that day's sheet, above Shacharit, instead of at the bottom of the day before. This happens only on the printed luach; the board keeps its order.
It applies to Maariv (and Kabbalat Shabbat) at or after plag hamincha. It does not apply to the morning fasts, so Maariv of Motzaei Rosh Hashana stays on the Rosh Hashana sheet and does not head Tzom Gedalia.
Two minyanim got the same room at the same time. Will I know?
Yes. When you save, shul.info checks the next 180 days for rows in the same room that overlap, using each prayer's length. It warns you, and you can save anyway.
The Conflicts tab lists every clash in the schedule. "Suggest fixes" checks options for you: another room that is free every time, a pause for the clash dates, a pause during one of your periods, or the smallest time shift that clears it. Every suggestion is checked so it does not create a new clash.
From next week Shacharit moves to 06:45. How do I keep this week right?
Zmanim and your opinions
Whose zmanim do you use?
Yours. In the admin panel's Zmanim tab you choose: alos hashachar (16.1°, 16.02°, 19.75°, 72 or 90 minutes), the dawn of the Magen Avraham, mincha gedola (half an hour zmanit, a fixed half hour, or the later of the two), tzais (8.5°, 6.45°, 3.65° or fixed minutes), plag hamincha (GRA or Ben Ish Chai), misheyakir (11.5°, 10.2° or fixed minutes), and the end of fasts.
A live preview shows the times your choices produce before you save. Every opinion flows to every place that shows a time: the board, the luach, the email, and every minyan anchored to that zman.
Our luach prints alos at 72 minutes but sof zman Shma MGA from 90. Is that possible?
We are in the hills. Our luach's sunrise is later than yours.
That is the horizon. A town in the hills often sees sunrise over a ridge to the east, while to the west the land falls away towards the sea. Your luach's sunrise accounts for that.
Set the horizon angle for sunrise and for sunset. You do not need to know degrees: type the sunrise time your own luach prints for a date you pick, and shul.info works out the angle and checks it against four dates across the year.
The horizon moves only what is seen: sunrise, sunset, and what is counted from sunset (candle lighting, Rabbeinu Tam, a fixed-minutes tzais). Sof zman Shma, chatzos, mincha gedola and plag keep their usual calculation.
Can shul.info match our luach for the whole year?Full plan
Yes. Upload pages of your luach under "Calibrate from your luach". It reads every printed sunrise and sunset and fits a skyline by direction, because the sun rises far to the north-east in summer and to the south-east in winter, and a ridge is a different height in each direction. Half a year of pages covers the whole year.
It also tests each opinion against the luach's other columns (alos, mincha gedola, plag, tzais, misheyakir) and proposes the one that matches. It shows how far each date is off, and nothing is saved until you press Save.
In London in June the sun never goes 16° below the horizon. What happens to alos?
You decide. By default such a zman is not shown that night. You can choose instead the fixed-minutes reckoning of the same opinion (72 minutes for 16.1°) or chatzos halayla.
Far enough north that the sun does not rise or set at all, the day can be computed at the nearest latitude that has a sunrise and a sunset, or at a latitude your rav names. A time computed this way carries a ≈ sign and a note.
Does the board know about the second day of Yom Tov?
The board and the screens
What do congregants see on the board?
Today's schedule with the next minyan highlighted, the day's zmanim, the coming Shabbat or chag, announcements, and the date in Hebrew and civil form. Shabbat shows the parsha and haftara; Rosh Chodesh, fasts and holidays are named by themselves.
Visitors can move to another date, switch language and theme, share by WhatsApp, and download the luach on the Full plan.

Can a gabbai change today's schedule from the wall board?Screen and Full plans
Yes. A gabbai unlocks the board with a personal 6-digit PIN (set in the Security tab). For 10 minutes they can pause or resume a row for today, shift today's time, add today's note, or set a new permanent time for a fixed row.
Five wrong PINs lock the board for 15 minutes and the owner gets an email. Removing a board or a gabbai ends the session at once.
Can the board remind people what to add in davening?
Yes. Turn on prayer reminders and the board, lobby screen and luach show what changes that day: Mashiv haruach or Morid hatal, Vesen tal umatar, Yaale veyavo, Al hanisim, Aneinu, Hallel, no Tachanun, Avinu Malkeinu, Ledavid, and tonight's Omer count.
They follow your nusach: Ashkenaz, Sefard, Edot HaMizrach or Teiman. The Maariv of the next day is shown on the evening before, the way it is said.

The assistant
What can the assistant do?Full plan
Tell it in plain words: "add a Mincha 15 minutes before sunset, Sunday to Thursday", "pause the Daf Yomi during bein hazmanim", "what does our Friday look like?". It can manage the schedule, rooms, periods, prayers, shiurim, announcements, pages, sponsorships and every setting.
Every schedule case on this page is within its reach: a minyan every 15 minutes, a bein hazmanim time beside the everyday one, Selichot by rite, Rosh Chodesh and fast-day shifts, earliest and latest limits, rounding, a Mincha that retires itself when sunset passes it, Maariv timed from Mincha, one card for Selichot and Shacharit, and a change for one day only.
Example
"In winter our 17:00 Mincha is too late; after that, Mincha is 15 minutes before sunset." The assistant proposes the condition on the 17:00 row and the matching sunset row, shows the times on a date either side, and waits for your confirmation on each card.
