How does the workday calculator work?
This tool has two modes. Count workdays calculates the number of working days (Monday–Friday) between two dates, excluding weekends. Add workdays takes a start date and a number of business days, then calculates the resulting date by skipping weekends. Both modes let you toggle weekend exclusion on or off.
Calculation method
The calculator iterates through each day between the start and end dates, counting only Monday through Friday when weekend exclusion is enabled. For "Add workdays" mode, it steps forward (or backward for negative values) one day at a time, only decrementing the counter on non-weekend days. This ensures accurate results regardless of how many weekends fall within the range.
