Calculating the exact difference between two dates is more complex than it seems — months have varying lengths, leap years add extra days, and business day calculations must exclude weekends. This tool handles all these edge cases accurately.
How to Use
Select two dates:
- Start date: The earlier or reference date
- End date: The later or target date
- Results: Broken down into multiple units
Business Days
Business days exclude Saturdays and Sundays. A typical month has about 22 business days. US holidays are not excluded automatically — only weekends.
Leap Year Rules
- Divisible by 4 → leap year
- Divisible by 100 → NOT a leap year
- Divisible by 400 → leap year (exception)
- 2024 is a leap year, 2100 is not, 2000 was
