About the birthday countdown
This tool counts down to your next birthday. Enter your date of birth and it shows the days, hours, minutes and seconds until your birthday, along with the age you will be turning. If today is your birthday, it celebrates with you. Your date of birth is saved only in your own browser so it is remembered next time — it is never uploaded to any server, keeping it completely private.
How Birthday Countdown works
How to use it
- Enter your date of birth.
- See the live countdown and the age you'll turn.
How it works
The tool takes the month and day of your birth date, finds the next time it occurs, and counts down to midnight on that day. The age you'll be turning is the difference between that birthday's year and your birth year.
Private and remembered
Your date of birth is stored in your browser's local storage, so the countdown is still here when you come back without re-entering it. Because it is saved locally and never sent to a server, your information stays private — and you can remove it any time by clearing the date field or your browser data.
