About the Birthday Countdown Calculator

This calculator finds the date of your next birthday — this year if it hasn't happened yet, or next year if it has already passed — along with the age you'll be turning.

How it works: The calculator builds this year's birthday date and compares it to today; if that date has already gone by, it rolls forward to next year's occurrence instead.

A leap-year birthday (February 29) is shown on February 28 in non-leap years so there's always a countdown date.
