See full years, months, and days, plus total weeks and days lived.

Check the next birthday

See the date, weekday, age turning, and time remaining.

Birthday calculator questions

How old am I today?

Enter your date of birth and select Calculate birthday. The first result shows your age in full calendar years, months, and days as of today.

How many days until my next birthday?

The next-birthday card shows the upcoming date, weekday, age you will turn, and a live countdown.

How are February 29 birthdays handled?

In leap years, the calculator uses February 29. In other years, it observes the birthday on February 28 for the age and next-birthday countdown.

Is my birth date saved?

No. The calculation runs in your browser. ScreenText does not save or receive the birth date you enter.

Are the zodiac and birth-year details exact?

The Chinese zodiac follows the lunar year containing the birth date. Zodiac traits, generation labels, and traditional birth symbols are included for fun and can vary by source.
