About the Birthday Countdown
The birthday countdown calculator shows a live, ticking countdown to your next birthday — down to the second. Enter your date of birth and the tool works out when your birthday next occurs, which day of the week it falls on, and how old you will turn.
It is perfect for planning a party, building excitement for kids, scheduling gifts and deliveries, or simply satisfying your curiosity. Combine it with our main age calculator to see your full age breakdown in years, months, weeks and days.
Born on 29 February?
If you were born on 29 February, your birthday only exists in leap years. In common years this countdown targets 1 March, the most widely used convention for leap-day birthdays. You can read more about the fascinating rules in our article on leap year birthdays.
Fun Birthday Facts
- Studies of birth records show that mid-September dates are consistently among the most common birthdays in many countries.
- 29 February is the rarest birthday of all — only about 0.068% of people are born on a leap day.
- In a group of just 23 people, there is a greater than 50% chance that two of them share a birthday — the famous "birthday paradox."
- Your birthday moves forward one weekday each year — and two after a leap day passes. If your birthday fell on a Tuesday this year, expect Wednesday or Thursday next year.
- Half-birthdays (exactly six months after your birthday) are popular for children whose birthdays fall in school holidays.

Parents use the live countdown to build excitement with kids in the final days before a party; event planners use it to schedule cake orders, invitations and venue bookings; and plenty of people simply keep the tab open on the big day to watch the seconds tick down to zero. Combine it with the age calculator to find out exactly how many days old you'll be when the balloons go up — or check whether your next birthday lands on a weekend and plan accordingly.
