Age CalculatorFLAGSHIP
Calculate exact age in years, months and days.
What this calculator gives you
Exact age in years, months and days, plus total days and the next birthday context.
Method
The calculation compares calendar components rather than dividing the day count by 365, so month lengths and leap years remain part of the result.
Example
If someone was born on January 15, 1990, their age on January 15, 2026 is exactly 36 years.
