How the Age Calculation Works

1. Basic Calculation of Age

  • Convert both dates to milliseconds since January 1, 1970 (Unix timestamp)
  • Find the absolute difference between these timestamps
  • Convert the difference to days by dividing by:
    • 1000 (milliseconds to seconds)
    • 60 (seconds to minutes)
    • 60 (minutes to hours)
    • 24 (hours to days)

2. Considerations for the Calculation:

  • Leap Years: Automatically handled by the JavaScript Date object
  • Month Lengths: Accounts for varying month lengths (28-31 days)
  • Time Zones: Calculations are done in the local time zone to avoid date shifts

3. Formula Used

Total Days = |Date2 - Date1| / (1000 * 60 * 60 * 24)

Where:
Date1 = Birth date
Date2 = Current date
1000 * 60 * 60 * 24 = Milliseconds in a day
