Count down to your next birthday
Choose your birth month and day. The calculator finds the nearest matching date on or after today and counts the calendar days between them.
If today is 9 September and your birthday is 10 September, there is 1 day left. On your birthday, the countdown is 0. Once it has passed, the calculator looks ahead to the next year.
A birthday on 29 February
This tool looks for an actual 29 February in the calendar, so it counts down to the next leap-year birthday. It does not substitute 28 February or 1 March.
If you celebrate on another date in a non-leap year, use the Days Until / Since calculator for that chosen date.
Frequently asked questions
Do I need to enter my birth year?
No. Only the month and day are needed to find your next birthday.
Does the countdown include today?
It measures the date difference: tomorrow is 1 day away and today is 0 days away.
Which time zone does Today use?
Today uses the local date on your device at the time you calculate. Clock changes do not add or remove a calendar day.
