Omer Counter
An Omer counter tracks Sefirat HaOmer, the 49 days from Pesach to Shavuot. It gives the count in days and in weeks and days, turns the day over at nightfall rather than midnight, and keeps a record of which days were counted, because whether the blessing still applies depends on that record.
Free, no sign-up, works offline, and nothing leaves this browser.
Set the date of the first night below and the count begins. The first night is the second night of Pesach; take the date from your own calendar or community, because this page does not compute the Hebrew date.
—
Nightfall sets when the day turns over, because the Jewish day begins in the evening. Actual nightfall varies by date and place; set it roughly and adjust if the day rolls over at the wrong time for you.
This keeps a record. It is not a halachic authority. It reports what you told it and applies the widely stated rule about a missed day; it does not rule on doubtful cases, does not know your community’s practice, and does not compute the Hebrew date or the true time of nightfall where you are. Practice differs between communities and on several points here. Where it matters, ask your rabbi rather than a web page.
Counting to 49 is easy. Knowing whether you may still say the blessing is not, because it depends on a day you may have missed weeks ago — and on whether you missed the night only, or the whole day.
Counting the Omer, Sefirat HaOmer, is the verbal counting of each of the 49 days from the second night of Pesach to Shavuot. The count is made at night, at the start of the Jewish day, and is stated in days and, from the seventh day, in weeks and days.

How to count the Omer with this counter
Set two things once, then record one tap a night for seven weeks.
Set the first night
The second night of Pesach. Take the civil date from your calendar or your community; the page does not work out the Hebrew date and will not guess one.
Set roughly when nightfall is
This is when the day turns over. It moves through the season and with where you are, so set it approximately and adjust if the day rolls at the wrong moment.
Count at night, and record it
Say the count as you normally would, then press Counted at night. The sentence is built for you in both forms, so there is nothing to work out.
If you forgot last night, count in daylight
Press Counted in daylight instead. That day is counted without the blessing, and the blessing resumes the following night.
If a whole day went by, keep counting
The count continues through all 49 days. Only the blessing stops, and the counter says so rather than leaving you to remember.
Read the grid to see the record
Every day shows how it was counted, so a gap is visible rather than something you have to reconstruct from memory in week six.
Where an Omer counter gets used
Anywhere the count has to be kept accurately for seven weeks running.
Keeping the nightly count
The main use: the count said at night, with the wording in both forms already assembled.
Knowing whether the blessing applies
The question that actually needs a record rather than a memory, especially by the fifth or sixth week.
After a night away or a late flight
The times a day gets missed. Record what actually happened and the counter carries the consequence forward for you.
Counting with children
A visible day number and a grid of forty-nine make the shape of the count easy to follow.
Teaching the count
The two forms are shown together, which is the part that takes explaining.
Somewhere with no signal
It works offline after the first load and sends nothing anywhere.
Why this is not a tally that happens to stop at 49
A tally counter can count to forty-nine. It cannot count the Omer, and the gap between those two statements is the reason this page exists. Three things make this count its own thing, and the third is the one that actually needs a tool.
One. The count is stated two ways, not one
From the seventh day onward the count is given in days and in weeks and days: “Today is the twenty-third day of the Omer, which is three weeks and two days of the Omer.” The weeks-and-days form is part of the count, not a decoration on it, which is why the number on its own is never the whole answer. The sentence is built for you as the days advance, so there is nothing to work out in your head at the moment you are meant to be counting.
Two. The day turns over at nightfall, not at midnight
The count is made at night, at the beginning of the Jewish day. So the count you make on a Tuesday evening belongs to Wednesday, and a counter running on a midnight boundary is wrong every single night rather than occasionally. The nightfall hour is therefore a setting rather than an assumption — real nightfall moves with the date and your latitude, and no page that does not know where you are should pretend otherwise.
Three. The blessing has a memory, and that is what a counter is for
This is the part an article cannot do for you. Whether you may say the blessing tonight does not depend on tonight. It depends on whether a day was missed — possibly weeks ago — and on how it was missed.
| What happened | That day | The following nights |
|---|---|---|
| Counted at night | With the blessing | With the blessing |
| Forgot at night, counted in daylight | Without the blessing | With the blessing — it resumes |
| Missed the night and the day | Not counted | Without the blessing, for the rest of the 49 |
| Unsure whether a day was missed | — | Commonly, with the blessing — ask |
The middle row is the one people get wrong in both directions: some stop saying the blessing when they did not need to, because counting in daylight preserves it, and some carry on saying it when a whole day went by uncounted. The counter keeps the record, so the answer is on screen rather than in your memory of a Tuesday in May.
And the count itself continues either way. Missing a day does not end it. All forty-nine days are counted through to Shavuot; only the blessing changes. That is why the grid keeps showing every day rather than stopping at the break.
Why the start date is asked for rather than worked out
The first night is the second night of Pesach. Turning that into a civil date needs a Hebrew calendar, and this page does not carry one. It could guess, and a guess presented as a date is worse than a question — a counter that starts a day late is wrong for seven weeks and never says so. So the date is yours to set, from your own calendar or your community’s, and everything else follows from it exactly.
What this does not do
It does not show the sefirah of the day, print the Hebrew or the transliteration, give times for nightfall in your location, or send a reminder — and the omission of the sefirot is deliberate rather than lazy: the associations are a Kabbalistic tradition with real variation in how they are presented, and a counting tool is not the right place to hand down a version of them. It is not a siddur; keep the text you say in front of you as you normally would. Everything is stored in this browser alone, so nothing is sent anywhere and clearing site data clears the record.

Frequently asked questions
What is counting the Omer?
Sefirat HaOmer is the counting of each of the 49 days from the second night of Pesach to Shavuot. Each night the day is counted aloud, and from the seventh day the count is given in weeks and days as well as in days.
How do I say the count in weeks and days?
From day seven onward, the count is stated both ways: “Today is the twenty-third day of the Omer, which is three weeks and two days of the Omer.” Divide the day number by seven for the weeks and the remainder gives the days. The counter assembles the sentence for you.
What happens if I forget to count the Omer one night?
If you remember during the following day, count then without a blessing, and you may count with a blessing again the next night. If the night and the day both passed without counting, you continue counting all 49 days but without a blessing from then on.
Does missing a day mean I stop counting?
No. The count continues through all 49 days to Shavuot either way. Missing a day changes whether the blessing is said, not whether the counting goes on, which is why this counter keeps showing every remaining day.
When exactly does the day change?
At nightfall, because the Jewish day begins in the evening rather than at midnight. The count made on a Tuesday evening belongs to Wednesday. Nightfall moves with the date and your location, so it is a setting here rather than a fixed hour.
Why do I have to enter the start date myself?
Because working out the second night of Pesach as a civil date needs a Hebrew calendar, and this page does not carry one. A counter that guessed and started a day early or late would be wrong for seven weeks without ever saying so, so it asks instead.
What if I am not sure whether I missed a day?
The commonly stated position is that where there is genuine doubt you may continue counting with the blessing. This is exactly the kind of question where practice varies and a web page should not be the authority, so ask your rabbi.
Does it show the sefirah for each day?
No, deliberately. The sefirot associated with each day come from a Kabbalistic tradition presented differently in different communities, and a counting tool is not the right place to hand down one version of them. Use your siddur for the text.
Will my count be there tomorrow night?
Yes. Everything is saved in this browser as you tap, so closing the tab or locking the phone loses nothing. It is tied to this browser on this device, and clearing site data clears the record.
Is this a substitute for a rabbi or a siddur?
No. It keeps a record and applies one widely stated rule about a missed day. It does not rule on doubtful cases, does not know your community’s practice, and carries none of the liturgy. Keep the text you say in front of you as you normally would.
