📅 What is a Workday Calculator?

A workday calculator (also called business days calculator) helps you count only weekdays (Monday through Friday) while excluding weekends and custom holidays. This is essential for project planning, invoice due dates, delivery estimates, HR calculations, and any business timeline that only considers working days.

Our calculator offers two modes: "Between Dates" counts workdays between two dates (excluding weekends and holidays), and "Add/Subtract Workdays" calculates a future or past date after adding/subtracting workdays. Both modes support custom holiday lists that are automatically excluded from calculations.

📌 Business Standard: Total Days = End Date - Start Date (difference). For June 7 to June 14, the difference is 7 days, not 8 (inclusive count).
