Calculate your exact age in years, months, and days, or determine the precise duration between any two calendar dates with automatic leap year adjustments.
How Calendar Age Calculation Works
Calculating age precisely is more nuanced than simple division because calendar months vary between 28, 29, 30, and 31 days, and leap years introduce an extra day every four years (with century exceptions). Our calculator accounts for exact calendar month boundaries to provide true chronological age.
