Next Birthday Countdown
A running countdown to the next birthday
This page counts forward from now to the next occurrence of the selected birthday. Once the target has passed for the current year, the timer moves to the following year automatically.
Use it for planning a date rather than calculating age. The detailed age tools answer how long someone has lived; this one answers how long remains until the next birthday target.
How this timer handles 29 February
For a birth date of 29 February, this timer uses 1 March in a non-leap year because that is how the calendar date normalises when 29 February does not exist. Local legal or personal anniversary conventions can differ, so edit the target if you prefer a different observance date.
Questions people ask
How does this handle someone born on 29 February?
This timer uses 1 March in ordinary years and 29 February in leap years. If you observe the birthday on a different date, use a custom date countdown instead.
Does the countdown reset itself after the birthday passes?
Yes, automatically — it moves on to the following year’s date without needing to be reset by hand.
