Frequently Asked Questions
Age is calculated by subtracting your date of birth from today's date. Days are calculated considering the exact number of days in each month (accounting for leap years). Our calculator gives you years, months, and remaining days.
A leap year has 366 days (February has 29 days) instead of 365. A year is a leap year if it is divisible by 4, except centuries which must be divisible by 400 (e.g., 2000 was a leap year but 1900 was not).
Different calculators handle the birthday itself differently — some count the birthday as Day 1, others count the day after. Our calculator counts from the day after birth.
Our calculator computes age as of today's date. For age on a specific past or future date, you would need to enter the birth date and manually calculate from the reference date.
