Subtracting Calendar Days vs. Weekdays
- Calendar Days: Calculates backward into history by the exact number of calendar days specified, regardless of weekends.
- Weekdays (Business Days): Bypasses Saturdays and Sundays. For instance, subtracting 5 weekdays starting on Monday will land you on the previous Monday.
Subtract Days Example
If you start on Monday, June 15, 2026 and subtract 10 days:
- Subtracting 10 Calendar Days: target is Friday, June 5, 2026.
- Subtracting 10 Weekdays: target is Monday, June 1, 2026 (excludes 4 weekend days).

Is there an limit to how far back I can compute?
You can enter up to 999,999 days, allowing you to trace date timelines back hundreds of years into historical periods.
Is my input sent to any servers?
