Business days & working days: the difference matters
Business days are the days on which work usually takes place – typically Monday to Friday. The calculator determines the net business days between two dates and removes Saturdays and Sundays, so you see the real working effort for projects or deadlines.
It is worth distinguishing working days from business days. In German law a working day (Werktag) is every day except Sundays and public holidays, so Saturday counts. Business days usually mean the five-day week without the weekend. This distinction matters for notice and delivery periods.
Public holidays in Germany are set by each federal state, so they differ noticeably between regions – for example Corpus Christi or Reformation Day. Bridge days – single working days between a holiday and the weekend – also affect the number of effective business days in a period.
Frequently asked questions
What is the difference between working days and business days?
Working days (Werktage) are all days except Sundays and public holidays, so Saturday is included. Business days usually mean the five-day week, Monday to Friday.
Are public holidays deducted?
The calculator reliably filters out weekends. Public holidays differ by federal state and should be accounted for separately for your region.
Why do holidays differ by federal state?
In Germany the states define their holidays. Days such as Corpus Christi or Reformation Day are public holidays in only some states.
What are bridge days?
Bridge days are single working days that fall between a public holiday and the weekend. With a few days off you can turn them into a longer break.
