Frequently asked questions
What week number is it now?
The current week number is shown at the top of this page. Year 2025 has 52 ISO weeks in total.
How many weeks are there in 2025?

The Czech Republic has 13 public holidays that must be taken into account when calculating working days and wages. These include both religious holidays (Good Friday, Easter Monday, Christmas) and state and civic holidays (State Foundation Day, Czechoslovak State Foundation Day). Unlike some countries, the Czech Republic does not have a substitute day system - if a public holiday falls on a weekend, no substitute day off is provided.
How many working days are there in 2026 in the Czech Republic?
The year 2026 has 365 days. From this number, 52 weekends (104 days) and 13 public holidays must be deducted. This results in approximately 248 working days. The exact number may vary depending on which days of the week the public holidays fall on and what the specific working hours are in the company.
What happens when a public holiday falls on a Saturday or Sunday?
If a public holiday falls on a weekend, no substitute day off is granted. The employee is entitled only to the regular weekend. Therefore, the hours for that public holiday are not counted, nor is an additional day off added.
Is the Day of Burning of Master Jan Hus (July 6) really a public holiday?
Yes, the Day of Burning of Master Jan Hus (July 6) is one of the 13 public holidays in the Czech Republic. It is a uniquely Czech holiday that commemorates the historical role of Jan Hus in Czech history and is defined in the public holidays law.
What is the standard working time fund per week in the Czech Republic?
The standard working time in the Czech Republic is 40 hours per week. When calculating overtime, wages, or vacation entitlements, this standard must be used, and it must also be applied when calculating remuneration for public holidays.
How are wages calculated on a public holiday?
The employee is entitled to wages at the same rate as on a regular working day. If the employee worked on that day, they would be entitled to their regular wage, or potentially a supplement for work on a public holiday according to the collective agreement or labor law regulations. A public holiday is therefore not a reason to reduce wages.
