Working Days Guide
What are working days?
Working days are weekdays when work is normally performed — Monday through Friday. Saturdays and Sundays are rest days in the standard business calendar. Poland uses a five-day system where the standard workweek is 40 hours spread across 5 days of 8 hours each. Working days also exclude legally mandated public holidays like New Year's Day, Constitution Day, National Armed Forces Day, and Christmas.
Public holidays in Poland
Poland has 13 legally mandated holidays: January 1st, Easter Sunday and Monday, May 1st and 3rd, Constitution Day (May 3rd), Whit Sunday, Corpus Christi, August 15th, November 1st and 2nd, November 11th, and December 25th and 26th. When a holiday falls on a weekend, employers are not required to provide a replacement day off, which distinguishes Poland from many other European countries.
Leave and absences
Employees in Poland are entitled to annual leave of at least 20 days with a permanent employment contract. Proportional leave applies for shorter tenure. Beyond vacation, employers may grant unpaid leave, request leave (4 days per year), or leave for child care. Planning leave requires considering both working days and holidays to maximize time off.
Practical applications
The working days calculator is essential for project planning with deadlines, calculating contract delivery times, planning business deliveries, and team management. It also helps check how many working days remain before vacation or the end of the tax year. Note that some industries (like retail or services) may have modified calendars due to work specifics.
