Hebrew birthday
Your next twelve Hebrew birthdays, year by year
Your Hebrew date of birth never changes, but the civil day it falls on moves back about eleven days every year. Enter your date of birth: you get your Hebrew date, your mazal, and the civil date of your next twelve Hebrew birthdays.
Sunset, and the place
Why the hour and the city change the answer
In the Hebrew calendar the day does not begin at midnight: it begins at sunset. That is the rhythm the Torah gives to Creation — “and there was evening, and there was morning, one day” — and it is still the rhythm of Shabbat, which enters on Friday evening rather than Saturday morning.
So a person born after sunset was born, in Hebrew terms, on the following day. Someone who comes into the world on a Tuesday at 10 p.m. carries a Hebrew date of Wednesday.
Most converters know this rule and ask you to tick a box: “born after sunset?”. The trouble is that you have to answer it yourself — and to answer it you would need to know at what time the sun set that day, in that place. Sunset does not fall at the same minute in New York, in Los Angeles, in London or in Jerusalem, and it shifts by more than an hour across the year. That is why this page asks for your city and your time instead of a checkbox: it works the sunset out for you.
Beyond the date
Your Hebrew month has a sign
A Hebrew birthday is not only a date to remember for a bar mitzvah or a yahrzeit. In Jewish tradition each Hebrew month carries a mazal — a sign — along with an element, a tribe of Israel, a precious stone and a letter. The mazal is read from the Hebrew month of birth, never from the civil one.
That is where the exact date starts to matter for more than the calendar: when a birth falls on the evening of the last day of a Hebrew month, one day of error moves you into the previous month — and gives you the wrong mazal altogether.
| Nissan (March–April) | Mazal Aries — fire |
| Iyar (April–May) | Mazal Taurus — earth |
| Sivan (May–June) | Mazal Gemini — air |
| Tamuz (June–July) | Mazal Cancer — water |
| Av (July–August) | Mazal Leo — fire |
| Elul (August–September) | Mazal Virgo — earth |
| Tishrei (September–October) | Mazal Libra — air |
| Cheshvan (October–November) | Mazal Scorpio — water |
| Kislev (November–December) | Mazal Sagittarius — fire |
| Tevet (December–January) | Mazal Capricorn — earth |
| Shvat (January–February) | Mazal Aquarius — air |
| Adar (February–March) | Mazal Pisces — water |
The civil dates above are approximate: the Hebrew calendar being lunisolar, no Hebrew month ever falls on exactly the same civil dates two years running.
A moving anniversary
Why your Hebrew birthday drifts every year
The Hebrew calendar follows the moon for its months and the sun for its seasons. Twelve lunar months fall about eleven days short of a solar year, so the Hebrew birthday moves back roughly eleven days each year in the civil calendar — then jumps forward by about a month in the years when a thirteenth month is added, seven times every nineteen years.
Which is why it is not enough to work the correspondence out once. Your Hebrew date of birth never changes; the civil day on which it returns changes every year.

Born in Adar? If you were born in Adar of an ordinary year, your 2027 Hebrew birthday is most often kept in Adar II, as for a bar mitzvah (Rema, Orach Chaim 55:10); some keep it in Adar I. Born in Adar I or Adar II, you keep your own month. The next-twelve-birthdays calculator applies this rule and tells you so.
On the day
What do you do on your Hebrew birthday?
In Jewish tradition, your birthday is not an ordinary day. The Jerusalem Talmud (Rosh Hashanah 3:8) teaches that a person does not easily fall on their birthday: on that day, your mazal stands by you. Hence a set of customs that many keep, in full or in part:
- Be called up to the Torah on the Shabbat before, or on the day itself if the Torah is read that day.
- Give tzedakah, in the morning and in the afternoon.
- Read the psalm of your year: the one numbered for the year of life that begins. Turning 30, you open Psalm 31.
- Take a quiet moment to look back on the past year, study a little more and choose a good resolution.
- Taste a new seasonal fruit and say the Shehecheyanu blessing.
- Gather the people you love around a joyful meal.
These customs were collected by the Chabad movement (Sefer HaMinhagim), and from 1988 the Lubavitcher Rebbe encouraged everyone to mark their Hebrew birthday this way. It is also the right day to read your mazal again.
Frequently asked
The Hebrew birthday in eight answers
How do I find my Hebrew birthday?
Convert the civil date, then check the hour: after sunset in your birthplace, the Hebrew date is the following day.
Why does the time change my Hebrew date?
Because the Hebrew day runs from sunset to sunset. And since sunset depends on the place and the season, the city matters as much as the hour.
What is a mazal?
The sign of Jewish tradition, given by your Hebrew month — with its element, its tribe of Israel and its stone.
Does my Hebrew birthday fall on the same civil date each year?
No — it moves back about eleven days a year, and jumps forward in the thirteen-month years.
And if I was born in Adar of a leap year?
The calculation tells Adar I from Adar II and shows the real month. Either way the mazal remains Pisces.
When is my Hebrew birthday in 2026 or 2027?
The calculator on this page gives the exact civil date of your next twelve Hebrew birthdays. The 5787 table shows where each Hebrew month falls between September 2026 and October 2027.
Is a Jewish birthday the same as a Hebrew birthday?
Yes. A Jewish birthday, or Jewish date of birth, is your date of birth on the Hebrew calendar, the calendar of Jewish tradition, and the day it comes back each year.
What do you do on your Hebrew birthday?
According to the customs collected by the Chabad movement: be called up to the Torah on the Shabbat before, give tzedakah, read the psalm numbered for your new year of life, study, take on a good resolution and taste a new fruit with the Shehecheyanu blessing.
And this is only the beginning
The Hebrew date is just the first line
Once the exact date is settled, the same calculation gives your mazal, the day of the week you were born on and what the tradition attributes to it, your planetary hour, your real rising sign — “the house of your life” — and the position of the seven planets at the minute of your birth, with the wheel of your sky to download.
