How do I use this page?
- Choose dates and whether to include the endpoints.
- Choose the holiday calendar, add custom days off and calculate.
- Review the count and list of exclusions.
What this page does not do: Polish calendar: 2011–2035; future years project the rules checked on 13 October 2026 and require review after legal changes. Christmas Eve starts in 2025; the one-off holiday on 12 November 2018 is included. Substitute days for Saturday holidays are not assigned: enter your employer’s chosen date as an additional day off. This counts Mon–Fri days after exclusions, not statutory working-time entitlement. Other countries require custom exclusions.

Theory — how does the calculator count business days?
The business days calculator counts business days between chosen dates, using an automatic Polish public-holiday calendar or your own list of excluded days. The Polish mode automatically excludes fixed holidays, Easter, Easter Monday, Pentecost and Corpus Christi. For the period from December 24 to 27, 2026, the result is zero days, because that range contains two holidays and a weekend. If a holiday falls on a weekend or is repeated in a custom exclusion list, it is not counted twice.
