Birthday Calculator | Find Age and Next Birthday

Age calculations in months can be tricky because not all months have the same number of days. Our calculator handles this complexity by counting full months from your birth date to the current date, with any remaining days shown separately.

Leap years add an extra day (February 29) to the calendar, which affects age calculations. If you were born on February 29, you technically only have a birthday every four years. For people born on other days, leap years ensure their birthday falls on the correct day of the week as the years progress.

Absolutely! Enter your birth date and then check when you'll reach milestone ages like 18, 21, 30, 40, 50, etc. The calculator will show the exact date you'll reach that age, helping you plan celebrations well in advance.
