Working Days Calculator India

The Working Days Calculator India counts the days you are actually rostered to work in a period, rather than the raw number of calendar days. It excludes the weekly offs you select and any holidays you enter, and shows the breakdown so you can see where each day went.

It is built around the fact that Indian working weeks vary widely. Monday to Friday, Monday to Saturday and alternate-Saturday schedules all exist side by side, and holiday lists differ by state, employer and year. The calculator asks for your pattern instead of assuming a national one.

1. Pick a mode: count days between two dates, or add working days to a date.
2. Select your dates or the number of working days to add.
3. Set your working week — many Indian offices use Monday–Friday or Monday–Saturday.
4. Paste your company holiday list, one date per line in YYYY-MM-DD format.

Working days = Calendar days − Weekly offs − Listed holidays

In "add working days" mode the calculator steps forward one day at a time from your start date and counts a day only when it falls in your working week and is not on your holiday list.

From 1 September to 30 September with a Monday–Friday week, a typical month gives 30 calendar days, about 22 working days and 8 weekly offs. Adding two company holidays reduces the working days to 20.

The same calendar month counted under different working weeks. A 30-day month with four full weekends is used for illustration; your month will differ.

The gap between the first and last row is five working days in a single month. That is why payroll pro-rating, notice periods counted in working days and project estimates all need the actual roster rather than a rule of thumb.

• Payroll pro-rating for a joiner or leaver in the middle of a month.
• Notice periods that your employer counts in working days.
• Project planning and delivery estimates in business days.
• Leave planning around a long weekend or festival cluster.
• Service-level commitments expressed in working days.

• Your weekly off pattern. Five-day, six-day and alternate-Saturday weeks all produce different totals.
• State holidays. Holiday lists are state-specific and change each year.
• Employer-declared holidays. Many companies publish their own list, often with a few optional or restricted holidays.
• Half days and shift rosters. These cannot be represented exactly as whole working days.
• Inclusive counting. Whether both end dates count changes the total by up to two days.

We deliberately do not ship a built-in Indian holiday calendar. National holidays are few — Republic Day, Independence Day and Gandhi Jayanti — while most other holidays are declared by individual states or employers and move from year to year. A built-in list would be wrong for most users, so the calculator asks you to paste your own company holiday list instead.

• Both the start and end date are included in the count.
• Holidays are excluded only when they fall on a working day.
• No national holiday list is applied unless you add one.

Half-days, alternate-Saturday policies and regional festival holidays vary widely. Use the custom working week and holiday list to match your own organisation as closely as possible.
