The birthday calculator tells you exactly how long until your next birthday — down to the live ticking second. It computes your exact turning age, the day of the week your birthday falls on, your half-birthday date, and a historical breakdown of past birthdays. No login required and all calculations run privately in your browser.
A half-birthday marks the midpoint of your birthday year — exactly 6 months from your birth date. For example, if you were born on May 14, your half-birthday falls on November 14. Our calculator computes the next upcoming half-birthday date and day of the week automatically.
People born on February 29 only have a true birthday every 4 years. On non-leap years, most countries legally celebrate on February 28 or March 1. Our calculator detects leap day birthdays and displays the next valid celebration date according to international convention.
Select your date of birth (DOB) from the calendar picker or enter it in your local date format.
Instantly see your live ticking countdown in days, hours, minutes, and seconds, plus your turning age and half-birthday.
