What is the Hebrew calendar?

The Hebrew calendar is a lunisolar calendar used in Judaism for religious purposes and in Israel as an official calendar. It combines lunar months (following the Moon's phases) with solar years (aligned with Earth's orbit around the Sun). Months alternate between 29 and 30 days, and leap months are added seven times in a 19-year cycle to keep holidays in their proper seasons.

Why doesn't my Hebrew birthday fall on the same Gregorian date each year?

The Hebrew calendar is lunisolar while the Gregorian calendar is purely solar, causing Hebrew dates to shift relative to Gregorian dates each year. A Hebrew birthday might occur 11 days earlier or up to 19 days later than the previous year's Gregorian equivalent. This is similar to how Easter changes dates each year.

What are the months in the Hebrew calendar?

The Hebrew calendar has 12 months in regular years: Nisan, Iyar, Sivan, Tammuz, Av, Elul, Tishrei, Cheshvan, Kislev, Tevet, Shevat, and Adar. In leap years (occurring 7 times every 19 years), a 13th month called Adar I is added before Adar (which becomes Adar II), totaling 13 months.

How do I celebrate my Hebrew birthday?

In Jewish tradition, Hebrew birthdays are significant spiritual milestones. Common observances include saying special prayers, receiving an aliyah (Torah honor) if synagogue attendance falls on that day, giving charity, reflecting on personal growth, and for milestone ages like 13 (bar/bat mitzvah) or 83, holding celebrations. Some choose to fast or engage in Torah study.

Does the Hebrew birthday start at midnight?

No, in the Hebrew calendar, days begin at sunset rather than midnight. Therefore, your Hebrew birthday actually begins the evening before the day shown on a calendar. For example, if your Hebrew birthday is the 15th of Nisan, the celebration begins at sunset on the 14th of Nisan.
