How it works
The calculator counts full calendar days between two dates. For example:
- January 1 → January 5 = 4 days
- March 15 → March 20 = 5 days
- Today → Today = 0 days
Calculations are based on dates only (no time) to ensure consistent results regardless of your timezone. Popular dates like Christmas or New Year's are automatically calculated for the nearest occurrence.
