How the business date calculator works
Pick a start date, choose whether to add or subtract days, enter how many days to move, and select what counts as a day — weekdays only, every calendar day, or a specific weekday (e.g. every 3rd Monday).

Weekdays skips Saturdays and Sundays. All calendar days moves the date by the exact number of days entered. Custom weekday advances only on the weekday you select — useful for “every N Tuesdays” style planning.
Worked example: starting Monday, Jan 6, 2025 and adding 10 weekdays lands on Monday, January 20, 2025 (weekends are skipped).
