Working Days Calculator

A working days calculator counts the weekdays between two dates and subtracts public holidays, so you get the number of actual working days. Both the start and end dates are included, which is the convention used for leave, notice periods, and project deadlines. Weekends are taken as Saturday and Sunday, and the holidays you enter are subtracted straight from the weekday total — which calendar of holidays applies is yours to supply, because it differs by country, by state and often by employer. For reference, 2026 holds 261 weekdays and 104 weekend days. Everything runs in your browser.

How to use it

1. Enter the start and end dates — both are counted.
2. Count the public holidays that actually fall on a weekday in that period, and enter that number.
3. See working days, plus the weekday and weekend split.
4. If your week is not Monday to Friday, add the extra non-working days into the same holidays field.

Examples

• 1–31 July 2026 → 23 weekdays, 8 weekend days.
• With 2 public holidays, that's 21 working days.
• August 2026 → 21 weekdays and 10 weekend days, before any holidays are taken off.
• 15 August 2026 falls on a Saturday, so counting it as a holiday would remove a working day that was never one.

Frequently asked questions

Are both start and end dates counted?

Yes. This calculator counts inclusively, so 1 July to 31 July includes both those days. That matches how leave applications, notice periods, and delivery timelines are normally counted.

Which days count as the weekend here?

Saturday and Sunday. If your workplace runs a different week — a six-day week, or Friday-Saturday weekends — add the difference through the holidays field to adjust the total.

How do I handle regional holidays?

Count the ones that actually apply to your office or state, check that each falls on a weekday, and enter that number. Holiday calendars vary by country, by state and by employer — many Indian companies publish a set of optional or restricted holidays on top of the fixed list — so a built-in calendar would be wrong more often than right. That is why the field is yours to fill rather than a hidden constant.

Can I calculate my notice period end date?

Yes — set the start date to your first notice day and the end date to your intended last day, then check whether the working-day count meets your contract's requirement. Note that many contracts count calendar days, not working days, so check the wording.

Do I need to check whether a holiday falls on a weekend?

Yes, and this is the mistake that catches most people. The holidays you enter come straight off the weekday total, so one that lands on a Saturday or Sunday is removed twice: once because it was already a weekend day, and again because you counted it. Independence Day in 2026 falls on a Saturday, for instance, so including it in an August count would take away a working day that never existed. Count only the holidays falling Monday to Friday.

Why does the same period give a different answer in another country?

Because both halves of the calculation are local. Saturday and Sunday are the weekend across most of the world, but several countries run a Friday–Saturday weekend, and a six-day week is still normal in parts of retail, construction and manufacturing. On top of that, no two national holiday calendars agree. This tool fixes the weekend at Saturday and Sunday and takes the holiday count from you, so if your week differs, add the extra non-working days to the holidays field — it is a plain subtraction, and anything you put there comes off the weekday total.

Is a notice period counted in working days or calendar days?

Read the contract, because both are used and the difference is large: 90 working days runs to roughly four months on the calendar, against three for 90 calendar days. Employment contracts commonly specify calendar days or whole months, while project timelines and service-level agreements more often work in business days. Where the wording says only 'days' with no qualifier, calendar days is the usual reading — but it is worth confirming in writing before you commit to a last working day.
