How Age Calculation Works (The Math Behind It)

For math enthusiasts, here’s how we compute your age precisely:

1. Year Difference: Current year – Birth year
2. Month Adjustment: If current month < birth month, subtract 1 year
3. Day Adjustment: If current day < birth day, subtract 1 month
4. Leap Year Handling: Extra day added for every leap year passed
5. Time Calculation:
   • Hours = (Total days × 24) + current hour
   • Minutes = (Total hours × 60) + current minute
   • Seconds = (Total minutes × 60) + current second

Example Calculation:
Born: 15 June 1990
Today: 20 May 2024
Age = 33 years, 11 months, 5 days
