Birthday Countdown
How many days until your birthday? See the countdown, the weekday your birthday falls on and the age you will turn.
Dates use your device’s calendar. If you were born on 29 February, the calculator counts your birthday on 28 February in years that are not leap years.
How the countdown works
The calculator finds the next date that has the same day and month as your date of birth and counts the days from today. On your birthday itself the countdown shows Today.
Example: on 6 November 2026, someone born on 17 May has 192 days to go — the next birthday is on Monday, 17 May 2027.
Half birthday
The half birthday is six months before or after the birthday. It is popular for children whose birthday falls in the holidays — the calculator shows the next one.
Count from another day
Change Count from to see how many days there will be until the birthday from a later date — useful for planning a party or a gift.
