Birthday countdown
How the birthday countdown works
By Toheed MehmoodReviewed How we check facts
In short
The countdown finds your next birthday (this year's if it has not happened yet, otherwise next year's) and counts the days from today. If your birthday is 27 August and today is 7 October 2026, your next birthday is Friday 27 August 2027, 324 days away.
- Longest possible wait
- 365 days (366 over a leap day)
- 29 February birthdays
- Counted on 1 March in common years
- Updates
- Every second, in your time zone
How to count down to your birthday
- Enter your date of birth. If you would rather not share the year, any year works; the age you are turning just will not be shown correctly.
- Watch the countdown: days, hours, minutes and seconds until midnight at the start of your birthday, in your own time zone.
- Check the weekday your birthday lands on, so you can plan the party for the right weekend.
Is the countdown to midnight or to the time I was born?
To midnight at the start of your birthday, on your device's clock. The big number is whole days left; hours, minutes and seconds tick down below it.
Counting down to a 29 February birthday
In common years the countdown targets 1 March, the date many leap-day babies celebrate. In leap years (2028, 2032, 2036) it counts to the real 29 February.
