Calculation for 3 weeks
Target Date = Today + 21 calendar days (Today is day 0)
Three weeks equals twenty-one calendar days, preserving the starting weekday. Weekday-only counting excludes weekends (21 business days counted).
Calendar-day addition counts every day, including Saturdays and Sundays, treating today as day zero. The first added day is tomorrow. In weekday-only mode, only Monday through Friday dates are counted toward the total; regional public holidays are not deducted automatically.
The calculator anchors to your local device clock and time zone. If you have an exact contract deadline, ensure you confirm any end-of-day cutoff hours separately.
