Workdays guide

Calculate workdays for fixed weeks and shift rotations

The number of workdays in a period depends on the work model. A fixed weekly pattern is counted differently from a rotation that repeats independently of weekdays.

Calculate workdays →

Five-day week

  • Count five selected weekdays, commonly Monday to Friday.
  • Adjust the actual weekdays if your workweek is arranged differently.

Six-day week

  • Count six selected weekdays.
  • The regular day off does not have to be Sunday and can be adjusted.

Custom shift rotation

  • Create a full sequence of work shifts and off days.
  • Choose a reference date for day 1.
  • The rotation then repeats independently of calendar weeks.

Holidays and leave

  • A holiday is deducted only when it falls on a planned workday and is treated as time off.
  • Leave also reduces planned workdays only.
  • A holiday and leave on the same day must not be deducted twice.
