How to use it
A business day here is Monday to Friday, minus public holidays from the calendar you choose. The first tool counts business days in a span; the inclusive switch decides whether the two dates you picked are part of it. The second tool steps forward (or backward, with a negative number) the given number of business days and shows the holidays it skipped.
Poland includes all statutory days off, with Easter Monday and Corpus Christi calculated from the Easter date and Christmas Eve from 2025. The US list uses federal holidays moved to Friday or Monday when they fall on a weekend. England and Wales uses bank holidays with substitute weekdays and the one-off holidays of 2020, 2022 and 2023.
Worked example: 1–30 April 2026, inclusive, Poland: Easter Monday (6 April) drops out with the weekends, leaving 21 business days.
Frequently asked questions
Is this a legal deadline calculator?
No. Courts and tax offices have their own rules for deadlines that end on a weekend or holiday. Use it for planning and check the rule that applies.
Why might a local holiday be missing?
Regional holidays, company shutdowns and holidays announced later are not in the lists.
Which time zone is used?
Dates are treated as calendar dates in UTC, so your browser’s time zone cannot shift a day.
