Understanding Age Calculation
Calculating age might seem straightforward, but it involves several complexities:
- Leap years: Every four years, February has 29 days instead of 28, affecting age calculations for people born on or around February 29.
- Varying month lengths: Months have different numbers of days (28-31), which affects how we calculate months and days in age.
- Calendar systems: Different cultures use different calendar systems, though this calculator uses the Gregorian calendar.
Our calculator handles these complexities automatically, giving you accurate results in years, months, and days.
