About the Age Calculator

Quick answers about how the calculation works and what your birth date can tell you.

How does this age calculator work?

This calculator uses the standard birthday-based system, so your age increases on your birthday. When showing months and days, it counts full calendar months first, then the remaining days.

How accurate is this age calculation?

Years, months and days are calculated from calendar dates. Since a birth time is not supplied, totals in hours, minutes and seconds are estimates that assume 00:00 UTC on the date of birth.

What else can my birth date tell me?

Your birth date can also reveal the day of the week you were born and your zodiac sign. You can find your star sign at WhatIsMySign.org.

How do I work out my age if my birthday has not happened yet?

Subtract your birth year from the current year, then subtract one more if your birthday is still ahead this year.

Does getting older automatically mean gaining weight?

Not necessarily. Metabolism, activity level and lifestyle usually matter more than age itself. If you’re curious how your weight compares with your height, try the BMI Calculator.

Why can people born in the same year have different ages?

Because one person may already have had their birthday this year while another has not. Enter a full date of birth for the exact result.
