Poland Working Days Calculator
Count working days between any two dates using Poland's national public holiday calendar. Poland observes 13 national holidays in 2025 — among the highest in the EU — including Epiphany on 6 January, Constitution Day on 3 May, and Corpus Christi on a Thursday in late spring. These holidays differ substantially from Western European calendars, making an accurate Poland-specific calculator essential for cross-border project planning.
Poland Working Days Calculator
Covers Poland's 13 national public holidays for 2025. Poland has one of the highest numbers of statutory public holidays in the EU. Easter Sunday is included as businesses are effectively closed, though it falls on a Sunday. Corpus Christi is a Thursday holiday unique among Poland's major EU trading partners. Dates for moveable feasts (Easter, Corpus Christi) change each year.
Formula
Working Days = Weekdays − National public holidays falling on weekdays
Count all Monday–Friday days in the range, then subtract any Polish national public holidays that fall on those weekdays. Poland's high holiday count — including Epiphany in January, Constitution Day in May, and Independence Day in November — makes accurate country-specific calculation especially important.
Worked Example
Scenario: A Warsaw manufacturer quotes a 25 working day production run starting Monday 28 April 2025.
Within this window: Labour Day (1 May, Thursday), Constitution Day (3 May, Saturday — no weekday deduction), and Corpus Christi (29 May, Thursday) both fall on weekdays.
25 working days + 2 weekday holidays (1 May + 29 May) = 27 weekdays forward
Result: deadline falls on ~4 June 2025
The early May window in Poland is especially holiday-dense. Polish workers often take the days between Constitution Day (3 May) and the weekend as informal bridge days. Confirm factory schedules directly for this period.
Common Mistakes
- Missing Corpus Christi (Boże Ciało). Corpus Christi always falls on a Thursday (60 days after Easter). It is a significant public holiday in Catholic Poland but is not observed as a holiday in most other EU countries. In 2025 it falls on 19 June.
- Forgetting Poland's May holiday cluster. Labour Day (1 May) and Constitution Day (3 May) create a natural bridge holiday window. Many Polish businesses close for the entire 1–4 May period, even when 2–3 May are working days. Confirm production availability directly.
- Assuming Epiphany is a working day. 6 January (Epiphany) is a national public holiday in Poland. It is not a public holiday in most of Western Europe, so cross-border planners often overlook it.
