Two modes: Days Between and Add/Subtract. Supports business days, presets, and multi-unit output.
Days Calculator Guide
A versatile tool with two modes: count the days between any two dates, or add/subtract a specific number of days from a starting date. Both modes support business-day awareness.
Days Between Mode
Pick a start and end date to see the total calendar days, business days (Mon–Fri), weekend days, full weeks and remaining days, and approximate months and years.
Add/Subtract Mode
Enter a base date and the number of days to add or subtract. Use the "Business days only" toggle to skip weekends. Quick presets (30, 60, 90, 180, 365 days) are provided for common scenarios.
