Quick answers about how the calculation works and what your birth date can tell you.
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.
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.
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.
Subtract your birth year from the current year, then subtract one more if your birthday is still ahead this year.
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.
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.
