Age Calculator
Calculate exact age
Frequently Asked Questions
How does the Age Calculator determine exact age?
Enter your date of birth and the calculator computes your exact age in years, months, and days. It accounts for varying month lengths and leap years to give a precise result down to the day.
Can I calculate age between two custom dates?
Yes. By default it calculates from your birth date to today, but you can set any two dates to find the exact time elapsed between them — useful for calculating age at a specific event or milestone.
Does the Age Calculator account for leap years?
Yes. The calculation correctly handles leap years (years divisible by 4, except centuries not divisible by 400). February 29 birthdays are handled accurately.
How is age calculated for someone born on February 29?
For leap day birthdays, the calculator counts full years normally. In non-leap years, the birthday is considered to fall on March 1 for age calculation purposes, following common legal convention.
Can I find out what day of the week I was born?
Yes. After entering your birth date, the result includes the day of the week. This uses the Gregorian calendar algorithm to determine the exact weekday for any date.
