Birthday Countdown
Count down to your next birthday with days, hours, and minutes remaining.
About this calculator
Birthday Countdown shows how long you have to wait until your next birthday, in days, hours and minutes. Enter the month and day of your birthday and, if you like, your name, and it starts a live countdown.
If today is your birthday, it says so. The countdown works out the next occurrence of the date, rolling to next year when this year's has already passed, and handles 29 February by using 1 March in non-leap years.
How to use it
- Enter your Birthday (month and day).
- Optionally add your name.
- Press Start Countdown and watch the time tick down.
How the countdown works
The tool builds the date of your birthday in the current year. If it has already passed, it uses next year. Time left = Next birthday − Now, shown as days, hours and minutes.
Worked example
A birthday on 25 December, counted from 8 November 2026
| Days left | 47 |
| Weekday | Friday |
The result is a live figure. It will be 46 days tomorrow.
