feiertage-und-kalender

The perpetual calendar computes public holidays for any year automatically — you define the rules once, and Klacks knows the holidays for all years to come.

How it works​

Every holiday is described by a short rule. There are two basic kinds:

  • Fixed dates in MM/DD format: 01/01 is New Year's Day, 08/01 the Swiss National Day, 12/25 Christmas.
  • Easter-based dates in EASTER+XX or EASTER-XX format: the Easter date is computed automatically using Gauss's Easter algorithm, and the holiday is defined as an offset from it. Examples: EASTER-02 = Good Friday, EASTER+01 = Easter Monday, EASTER+39 = Ascension Day, EASTER+50 = Whit Monday, EASTER+60 = Corpus Christi.

In addition there are fixed dates with weekday shifting (MM/DD+XX+WW or MM/DD+XX-WW) for holidays like "first Thursday in November" (11/01+00+TH) or "last Monday in May" (05/25+00-MO).

With SubRules you shift a holiday automatically when it falls on a particular weekday — e.g. SA+2;SU+1: if the day falls on a Saturday or Sunday, it moves to the Monday. Multiple rules are separated with ;.

For each rule you also record a name and description (multilingual), country and canton/state, plus the checkboxes Statutory holiday and Paid.

Good to know​

  • The weekday abbreviations are English: SU, MO, TU, WE, TH, FR, SA.
  • SubRules are mainly intended for moving holidays from the weekend to the next working day.
  • The Paid checkbox is relevant for payroll calculation.
  • Country and canton/state let you handle regional differences — Good Friday, for example, does not apply in all Swiss cantons (exceptions: VS, TI).
  • The pre-installed calendar packages for countries and Swiss cantons are locked against deletion; your own, self-created calendar selections can be deleted at any time.
