Birthday countdown
until you turn – on a –
Your year since the last birthday — the ring is today.
See all your years at once, drawn in weeks.
How the countdown works
The tool finds your next birthday by true calendar arithmetic: your birth month and day projected into the current year, or the next one if it has already passed — with February 29 birthdays mapped to February 28 in common years and restored in leap years. The count is exact days in your timezone, so it ticks over at your midnight, not a server's.
The dots above tell the fuller story: your personal year so far, filled day by day since the last birthday, with today ringed. Between birthdays there are 52 weeks — the unit this whole site is about. If the countdown made you feel the year moving, the life in weeks view shows all of them at once, and the age calculator gives the precise tally.
Questions
How many days until my birthday?
Enter your date of birth above — the countdown shows exact days (and the weekday it lands on), computed in your timezone and correct across leap years, including February 29 birthdays.
My birthday is February 29. When do I celebrate?
In common years the countdown targets February 28 by convention; in leap years, the true February 29. The tool switches automatically.
Why does it show my age in weeks too?
Because birthdays are milestones on a longer calendar. One year is 52 dots on the grid this site is named after — see yours on the life in weeks calculator.
