WorkdayCalculator: Date Range

WorkdayCalculator counts the working days between two dates, or works out a deadline by adding workdays to a start date. Set your own work week and your own days off for project plans, pay periods, notice periods and delivery dates.

• Count workdays, non-working days and calendar days between two dates

• Find a deadline: start date plus N workdays, or count back with a negative number

• Choose Monday–Friday, Sunday–Thursday or Monday–Saturday, or switch each weekday on or off

• Make named days-off lists for holidays, leave or closures; add single dates or whole ranges

• Your lists stay on this device; no holiday calendar is built in, so you decide what counts

• Start fast with presets: this workweek, a two-week sprint, this month or a 14-day billing window

• Save named scenarios with notes and load them again later

• Share a clear summary straight from the result card
