FAQ

How does the Hebrew Birthday Calculator work?

The calculator uses the Hebcal API to convert your Gregorian birth date into the corresponding Hebrew birthday, and then calculates additional details including the upcoming Hebrew birthday, day of the week, special observances, and astrological associations.

Why do the Hebrew and Gregorian birthdays differ?

The Hebrew calendar is lunisolar, so its dates do not align exactly with the Gregorian calendar. This means that your Hebrew birthday can fall on a different Gregorian date each year.

Yes, the calculator uses real-time data from the Hebcal API which takes into account leap years and other nuances of the Hebrew calendar to provide accurate results.
