Exemple Résolu
Born June 1990, current date March 2026.
- 01Total months = (2026 - 1990) x 12 + (3 - 6) = 432 - 3 = 429
- 02Age in years = floor(429 / 12) = 35
- 03Remaining months = 429 - 35 x 12 = 9

Questions Fréquentes
How is age calculated in different cultures?
In Western countries, age starts at 0 at birth and increases on each birthday. In Korean age tradition, everyone is considered 1 at birth and gains a year on New Year's Day (not their birthday), making Korean age 1-2 years higher than Western age.
Why does this use months instead of exact days?
This simplified calculator works with year and month inputs for ease of use. For exact day-level precision, you would need full date inputs including the day of the month.
How many days are in a year on average?
A calendar year has 365 days. Leap years have 366 days and occur every 4 years (with some exceptions). The average accounting for leap years is 365.25 days, or approximately 52.18 weeks.
How do I calculate someone's exact age in days?
Multiply the number of complete years by 365, add the days from extra months, and account for any leap years in that span. For a quick estimate, multiply years by 365.25. For example, 35 years is approximately 35 × 365.25 = 12,784 days.
