Birthday Countdown: How Many Days Until My Birthday?
Your date in, the wait out: days to go, a clock running down to the second, the weekday it lands on and, if you give the year, which birthday it is. It all runs in your browser, and nothing you type leaves the page.
Days until a birthday on the 1st of each month
A quick guide, counted from Saturday, October 17, 2026. Born mid-month? Add the days past the 1st.

How the count works
Today is left out. A birthday tomorrow reads 1 day; on the day you get a happy birthday and a count to the next one. The clock under the big number stops at midnight when your birthday starts, on your own phone or laptop clock.
Friends abroad hit the day earlier or later: someone in Sydney is already celebrating while New York is still at breakfast the day before. Leap-day babies count to February 28 in common years, so the next one shown is February 28, 2027.
Why your birthday changes weekday
A common year is 52 weeks and 1 day long. So a birthday slides one weekday later each year, or two when a February 29 falls in between. July 4 is a Sunday in 2027 and a Tuesday the year after. For a hundred years of weekdays for one date, try the day of the week calculator.
Share your countdown
Once you press Count down, the address bar carries your date, as in /birthday-countdown/?b=03-14&n=Sam. Drop that link in the family group chat and everyone sees Sam's days left from their own date. Untick the year box first if you would rather keep your age out of it.
Birthday countdown questions
How many days until my birthday?
Put your date in the box at the top; the answer appears straight away. A January 1 birthday, for example, is 76 days off as of October 17, 2026.
How many sleeps until my birthday?
Same number as the days. Three days to go means three bedtimes, the last one on the night before.
How old will I be on my next birthday?
Leave the year in and the countdown names it, your 30th or your 65th. Untick the year and you just get the days.
What if my birthday is February 29?
Then the count runs to February 28 in common years, as the age calculator does; plenty of leap-day people pick March 1 instead. The next real February 29 is in 2028.
