How the Calculator Works

The date calculator uses accurate date logic to adjust for leap years, different month lengths, and transitions between months or years.

Date Calculation Process

  1. Years First: Adjusts for any complete years included in your calculation.
  2. Months Next: Manages the differences between months with varying days.
  3. Days Last: Adds or subtracts the exact number — in this case, 100 days.
