How many days until your birthday?
Enter your date of birth and the calculator finds your next birthday: the full date, the weekday it falls on and how many days, weeks and months are left, with a live clock counting down the hours, minutes and seconds. It also shows the age you’ll turn and the weekday you were born.
A next birthday calculator: how many days until my birthday, and what day my birthday is this year.
How the countdown works
The count runs from today on your device to your next birthday, not including today. If your birthday is today, the calculator wishes you a happy birthday and counts to the one after next year. The live clock counts down to midnight at the start of your birthday in your time zone.
Born on 29 February?
In years without 29 February, your birthday is counted on 28 February, which is also when your age changes in this calculator and the age calculator. Some people celebrate on 1 March instead; the countdown simply shifts by a day.
Make it a plan
- Pick a weekend near the date for a party, now that you know the weekday.
- Share the countdown with friends who like surprises.
- Planning a child’s first birthday? The baby age calculator shows the date and the baby’s age in weeks and months on the way.
For any other date, from exams to holidays, use days until, and for the big day itself, the wedding countdown.
Your date of birth is worked out on your device and never stored or sent anywhere.
