What is the Working Days Between Dates?
This calculator counts how many working days fall between two dates. It walks through every date in the range, excludes the weekly offs you select and the holidays you enter, and reports the working-day total alongside the calendar days, the weekly offs and the holidays it removed.
Seeing the breakdown matters as much as the total: it lets you verify the count rather than trust it, which is exactly what you need when the number feeds into payroll, a notice period or a client commitment.
How to use this calculator
- Choose the start date and the end date.
- Select your working week.
- Add holidays that fall in the range, if any.
- Read the working-day total and the breakdown below it.
How the calculation works
Working days = Calendar days − Weekly offs − Holidays on working days
Worked example
Between 1 April and 15 April with a Monday–Friday week, there are 15 calendar days. If four of them fall on a weekend, you get 11 working days — 10 if one company holiday falls in the range.
More India-specific examples
Realistic ranges counted on a Monday–Friday week. The figures assume no public holidays unless stated.
| Range | Calendar days | Weekly offs | Working days |
|---|---|---|---|
| 1 to 15 April | 15 | 4 | 11 |
| 1 to 30 April | 30 | 8 | 22 |
| 1 April to 30 June | 91 | 26 | 65 |
| 1 to 30 April with 2 holidays | 30 | 8 | 20 |
Switch to a Monday–Saturday week and the second row rises from 22 to 26 working days, because only the Sundays are removed.
When this calculator is useful
- Counting the working days in a notice period your employer measures in office days.
- Billing a client for business days worked in a period.
- Checking whether a project window is long enough before committing to it.
- Working out attendance or payroll days for a partial month.
- Planning leave and knowing exactly how many working days you are consuming.
Factors that change your result
- Inclusive counting. This calculator counts both the start and the end date; some policies exclude one.
- Your working week. Five-day and six-day weeks differ by roughly four days a month.
- Holidays falling on a weekly off. These are not double-counted, so they do not reduce the working-day total.
- Regional variation. Two offices of the same company can have different holiday lists.
India-specific notes
Because Indian holiday lists are set by state and by employer, the only reliable source for a working-day count is your own company calendar. Ask HR for the published list for the year and enter the dates that fall inside your range — that is the difference between an approximate answer and one you can defend.
Assumptions
- The end date must be on or after the start date.
- Both dates are included in the count.
Limitations
Only the holidays you enter are excluded. Regional and employer-specific holidays are not assumed, because they vary across India.
