Your age is calculated by comparing your date of birth with today’s date. The calculator counts your completed years first, then adds the remaining months and days.
For example, someone born on July 8, 1990 is 36 years, 1 month and 28 days on the calculation date shown.
Unlike a simple year subtraction, this method accounts for birthdays, different month lengths and leap years automatically.
A common mistake is to subtract birth year from the current year. That only gives an approximate age.
Your exact age depends on whether your birthday has already happened this year.
| Date of Birth | Age |
|---|---|
| March 11, 2026 | 0 years |
| June 18, 1990 | 36 years |
| October 13, 1964 | 61 years |
| June 1, 2016 | 10 years |
| December 11, 2000 | 25 years |
Your age is more than just the number of birthdays you’ve celebrated. Every day adds to the months and days since your last birthday.
For example, you may be 36 years, but also 36 years, 7 months and 30 days. That extra precision is useful for forms, records and personal milestones.
Leap years are also included automatically, so birthdays on February 29 are handled correctly.
An age calculator is useful whenever you need to know someone’s exact age instead of an approximate number of years.
