About Date Calculator
Date Calculator offers three modes: calculate the number of days between two dates, add days to a date, or subtract days from a date. In the between mode, it shows weekdays, weekends, and a week breakdown. The add/subtract modes support workday-only calculations.
How to Use
1. Select a mode: Between Dates, Add Days, or Subtract Days. 2. For Between Dates: enter start and end dates to see total days, weekdays, weekends, and week breakdown. 3. For Add/Subtract: enter a start date and number of days. Optionally enable workday-only mode. 4. Use the Today button to quickly set the start date to today.
Workday Mode
When workday mode is enabled in Add or Subtract mode, the calculator skips weekends (Saturday and Sunday). This is useful for calculating delivery dates, project deadlines, or business day counts.
