Working Business Days Calculator

Calculate net working business days (Mon-Fri) between dates excluding weekend days.

Overview

Calculates net business working days between two calendar dates, automatically excluding Saturdays, Sundays, and public bank holidays.

Formula & Calculation Method

Working Days = Total Calendar Days - (Weekend Days + Public Holidays)

Calculates standard Monday-through-Friday commercial work days, supporting 5-day and 6-day work week schedules.

Worked Example: Working Days in October 2026 (31 Calendar Days)

Inputs: Start = October 1, 2026 | End = October 31, 2026 | 5-Day Work Week | Public Holidays = 2 Days

  • Total calendar days = 31 days
  • Weekend days (Saturdays and Sundays) = 9 days
  • Declared national holidays falling on weekdays = 2 days (Gandhi Jayanti, Dussehra)
  • Net working business days = 31 - 9 - 2 = 20 Working Days

Summary: Calendar Days = 31 | Weekend Days = 9 | Holidays = 2 | Net Working Days = 20 Days (160 Work Hours)
