When Is My Birthday? Next Birthday Countdown

“When is my birthday?” by date of birth is really two questions: how many days until it, and what day of the week it lands on this year. A birthday calculator answers both instantly.

How the countdown works

Enter your date of birth and the tool finds the next occurrence of your birthday. If this year’s has passed, it rolls forward to next year, then counts the exact days, hours, minutes and seconds remaining.

What day will my birthday fall on?

Because the weekday of your birthday shifts each year (by one day, or two after a leap year), it’s handy to know in advance whether it lands on a weekend — perfect for planning a party.

Count down to someone else’s birthday

Enter a friend or family member’s date of birth instead to never miss their big day again.

Make it a habit

Bookmark the countdown and check back as the day approaches — watching the number shrink is half the fun.
