Hebrew Date Converterממיר תאריכים עברי

Ever wondered what your Hebrew birthday is, or which Gregorian date a Hebrew anniversary falls on this year? The two calendars don’t line up neatly — the Hebrew calendar follows the moon and the sun at once, so a Hebrew date drifts across the Gregorian year from one year to the next. That’s exactly what a Hebrew Date Converter is for. Enter a date above and get its exact equivalent in seconds, in Hebrew script and English.

How to use the Hebrew Date Converter

The converter works both ways, and it’s built to be simple:

• Gregorian to Hebrew: pick any calendar date and instantly see the Hebrew date — in traditional Hebrew script (with gematriya numerals), in English transliteration, and with the day of the week.
• Hebrew to Gregorian: choose a Hebrew day, month, and year and get the matching Gregorian date. The month list shows Adar I and Adar II only in leap years, so you can’t pick a month that doesn’t exist.
• Today button: jumps straight to today’s Hebrew date.
• After-sunset toggle: since the Hebrew day starts at sunset, tick this for evening dates and the converter advances to the correct day.

No sign-up, no cost — just an accurate answer whenever you need one.

What is the Hebrew calendar?

To understand why you need a Hebrew Date Converter in the first place, it helps to know how the Hebrew calendar works — because it’s quite different from the Gregorian one.

The Hebrew calendar is lunisolar: its months follow the cycle of the moon, while the year stays aligned with the solar seasons. Each month begins with the new moon and lasts 29 or 30 days, making a 12-month lunar year about 354 days — roughly 11 days shorter than the solar year. Without a correction, the holidays would slowly drift through the seasons. You can read more on Wikipedia’s Hebrew calendar overview.

• Days begin at sunset. A Hebrew date runs from nightfall to the next nightfall — which is why Shabbat and holidays start in the evening.
• The year count is long. It counts from the traditional date of creation, so 2026 CE falls mostly in the Hebrew year 5786.
• The new year is in autumn. Rosh Hashanah falls in September or October, though the months are traditionally numbered from Nisan in spring.

Because of all this, there’s no simple formula to line the two calendars up in your head. A converter does the exact arithmetic for you.

Why convert Hebrew dates?

A Hebrew Date Converter isn’t just a curiosity — people reach for one for real, meaningful reasons:

• Finding your Hebrew birthday — it lands on a different Gregorian day each year, and many people mark it or get an aliyah to the Torah on the nearest Shabbat.
• Yahrzeit (memorial) dates — observed by the Hebrew date, so families convert each year to know when to light the candle and say Kaddish.
• Bar and bat mitzvah dates — set by the Hebrew birthday, so families convert to find the exact date and the week’s Torah portion.
• Anniversaries and life events — weddings, a brit, and other milestones are often remembered by their Hebrew date.
• Holidays and planning — see which Gregorian day a Jewish holiday lands on next year, or plan a trip to Israel around the Hebrew calendar.

How Hebrew leap years work

Here’s where a Hebrew Date Converter really earns its keep. To keep the lunar months aligned with the solar year, the calendar adds a whole extra month seven times across a 19-year cycle (the Metonic cycle). In those seven leap years, Adar I is inserted before the regular Adar, which becomes Adar II.

So a leap year has 13 months and about 384 days, while a common year has 12 months and about 354 days. On top of that, Cheshvan and Kislev can each have 29 or 30 days depending on the year, so Hebrew years come in six possible lengths. That’s precisely why converting by hand is so error-prone — and why a properly built converter is worth using. Ours determines leap years and month lengths correctly for every year.

Finding your Hebrew birthday

One of the most popular uses of a Hebrew Date Converter is finding your Hebrew birthday. Because the Hebrew year is shorter than the solar year and then corrects with leap months, your Hebrew birthday lands on a different Gregorian date each year — usually drifting earlier, then jumping back after a leap year.

Just enter your Gregorian date of birth above and read off the Hebrew date — that’s your Hebrew birthday. From then on, you can convert it forward to see which Gregorian day it falls on in any year. Many people mark the occasion, and it’s traditional to be called to the Torah on the Shabbat around your Hebrew birthday.

Using the converter for a yahrzeit

One of the most meaningful uses of a Hebrew Date Converter is finding a yahrzeit — the anniversary of a loved one’s passing, observed each year on its Hebrew date. Because it follows the Hebrew calendar, the yahrzeit falls on a different Gregorian day every year, which is why families turn to a converter annually to know when to light the memorial candle, recite Kaddish, and visit the grave. Enter the Hebrew date of passing, then convert it forward to see when it falls this year. If the passing occurred after sunset, the Hebrew date is already the next day — a detail the after-sunset toggle handles for you.

Bar and bat mitzvah dates

A bar or bat mitzvah is tied to the Hebrew birthday, not the Gregorian one — traditionally 13 for boys and 12 or 13 for girls, counted on the Hebrew calendar. That makes a Hebrew Date Converter the natural first step: convert the child’s Gregorian birth date to find their Hebrew birthday, then convert that forward to the relevant year to pin down the exact Gregorian date. From there, families can identify the Shabbat when the child is called to the Torah and the weekly portion they’ll read.

Two calendars, side by side

It helps to see why the two systems need a Hebrew Date Converter to bridge them at all. The Gregorian calendar is purely solar: 365 days, a leap day every four years, and months fixed at 28 to 31 days that have nothing to do with the moon. The Hebrew calendar is lunisolar: its months are true lunar months that begin with the new moon, and its year is kept in step with the seasons by adding a whole leap month seven times every nineteen years.

The result is two calendars that roughly agree on the length of a year but disagree on almost everything else — where months begin, how many there are, when the year starts, and when the day itself turns over. A single Gregorian date can land on different Hebrew dates in different years, and the reverse is just as true. There’s no shortcut to reconcile them in your head, which is the entire reason a Hebrew Date Converter exists: it applies the precise rules of both systems so you don’t have to.

Hebrew dates and Jewish holidays

Every Jewish holiday is fixed to a Hebrew date, which is why they seem to “move” on the Gregorian calendar — Passover always begins on 15 Nisan, but that might be late March one year and mid-April the next. A Hebrew Date Converter lets you work the other way too: pick a Hebrew date like 25 Kislev (the first night of Hanukkah) and see exactly when it falls this year or any year. For anyone planning travel around the holidays — especially a trip to Israel, where the whole country moves to the rhythm of the Hebrew calendar — that’s especially useful.

Reading a Hebrew date

When the converter shows a result in Hebrew script, you’re seeing the traditional way dates are written — with gematriya, where Hebrew letters double as numbers. The day and year are spelled in letters rather than digits: hey (ה) is 5, and תשפ״ו spells 786 for the year 5786, with small marks (a geresh ׳ or gershayim ״) signalling that letters are read as a number. So 5 Av 5786 appears as ה׳ אב תשפ״ו. You don’t need to read gematriya to use the tool — it always gives the plain English transliteration too — but it’s exactly how the date would appear on a Hebrew birthday certificate, a ketubah, or a gravestone.

A brief history of the Hebrew calendar

The Hebrew calendar is one of the oldest continuously used calendars in the world. For much of ancient history it was based on observation: each new month was declared when witnesses reported seeing the new moon, and leap months were added to keep the festivals in season. Around the 4th century CE, tradition credits the sage Hillel II with publishing the fixed, calculated calendar still used today — a mathematical system that set month lengths and the 19-year leap cycle so communities everywhere could keep the same dates. That calculated system is exactly what a modern Hebrew Date Converter reproduces, which is why the results are consistent and precise.

From the calendar to the country: live the Hebrew year in Israel

There’s a difference between reading the Hebrew calendar and living by it — and there’s really only one place you can do the second: Israel, the one country in the world that runs on the Hebrew calendar. There, the week builds toward Shabbat, the year turns on Rosh Hashanah and Passover, and the dates on this converter stop being abstractions and become the rhythm of daily life.

That’s what a Masa program offers. You can live in Israel for anywhere from a few weeks to ten months — studying, interning, volunteering, or immersing — with your own apartment, a built-in community, Hebrew classes, and a grant included. You’ll celebrate the holidays where they began, count the weeks toward Shabbat the way the whole country does, and pick up the Hebrew calendar so naturally that you’ll stop needing a converter at all. If exploring your Hebrew date sparked something, our guide to connecting with your Jewish identity in your 20s is a great next read — and you can see whether you’re a Tel Aviv or Jerusalem person, get a feel for the cost of living in Israel, and pick up the local habits in our guide to not looking like a tourist.
