Background: date rules

Holiday dates are defined in three ways: a fixed day of the month, a weekday position such as the fourth Thursday of November, or a calendar calculation such as the date of Easter. Counts are in whole calendar days from the start date, and the date is the calendar date, not adjusted for your time zone or for days a workplace observes instead.

Assumptions and limitations

  • Counting on the holiday itself gives 0
  • After the date has passed this year the next year's date is used

If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for counting from to confirm this.
