Working Days Calculator India

About This Calculator

The working days calculator for India counts the business days between two dates using India's national holiday calendar. It takes the full span of days, removes Saturdays and Sundays, and then removes Indian national holidays that fall on a weekday.

This is useful for HR and payroll teams, businesses quoting delivery or service timelines, and anyone tracking notice periods, leave, or administrative deadlines in India. Because these are all measured in working days rather than calendar days, weekends and public holidays have to be taken out to get an accurate figure.

The result shows the total days in the range, the number of weekend days, the number of national holidays on weekdays, and the resulting working days. Both the start and end dates are included, and a reversed range is handled gracefully.

The holiday list currently covers India's date-fixed national holidays — Republic Day, Independence Day, and Gandhi Jayanti. India also observes many gazetted and regional festivals whose dates move each year with the lunar and religious calendars; these are being added, so for now treat the result as accounting for national holidays plus weekends, and adjust for any regional festival specific to your state.

To use it, choose a start date and an end date and press Count working days. For other countries, the standard working days calculator uses that country's holidays, and business days between dates is handy for project planning.

How It Works

  1. Enter a start date.
  2. Enter an end date.
  3. Click “Count working days”.
  4. View the business days, with weekends and holidays removed.

Formula & Methodology

The result is worked out as follows:

Working days = all days − weekends − public holidays

Each day in the range, including both endpoints, is checked. Saturdays and Sundays are removed, then Indian national holidays that fall on a weekday are removed. A holiday already on a weekend is not counted twice, leaving the working-day total.
