Hebrew Birthday Calculator
Find the Hebrew date of a birthday and its upcoming civil dates. Choose the sunset and leap-year assumptions yourself; no account is needed.
Your result will appear here. You can download it without registering.
How to use this tool
Use the civil date at the place of birth. Choose whether the birth was before or after local sunset. For an uncertain time, compare both results and retain the uncertainty in your records.
A practical example
A birth on September 16, 2023, before sunset converts to 1 Tishri 5784. After sunset it converts to 2 Tishri.
Common questions
Why does the sunset choice matter?
The Hebrew date changes in the evening. This tool uses your before/after-sunset choice; it does not calculate sunset from a location.
What happens to an Adar birthday?
Select how a common-year Adar date should appear in a leap year. This is a family calendar planning tool; dates for religious milestones may need separate guidance.
Keep the next step small
Take the result to one relative, check one source, or organize one small collection.
