Plan around the next birthday date
The calculator finds the next occurrence of the birth date on or after your reference date. It also shows the weekday, which helps when planning a celebration.
For a birthday on 29 February, this tool uses 1 March in years without that date. This is a stated calculation choice, not a rule for legal age.
How to use this tool
- Enter the birth date.
- Check the reference date.
- Read the next birthday, weekday and days remaining.
Example
With a reference date of 1 June and a birthday on 15 June, the result is 14 days remaining. On the birthday itself, it shows zero.
Common questions
