Holidays Recurrence Rules

Scroll Prev Up Next More
In the center of the recurring holidays information panel is a multi-tab control that is used to specify the recurrence rule to use to calculate the date of each holiday, year after year.

 

Holidays copied from the worldwide public holidays database

 

If the currently-selected holiday was copied from the worldwide public holidays database, then that holiday's recurrence rule cannot be modified, and this is indicated by the recurrence rule header caption, as shown on the right.

 

If you want to be able to modify the rule of a selected holiday, then you can right-click on that holiday and select the remove ancestor option from the popup menu that then appears. You will then be able to modify the rule of that recurring holiday but, of course, that holiday will then be excluded from any further holidays synchronizations.

 

You can, however, use holiday name variations to achieve the tweaks you might want to apply to these copied holidays, without losing the benefits of subsequent holidays synchronization, such as keeping only the day in lieu holiday or keeping only the first day of a multi-day holiday. For detailed examples, see the topic on tweaking holidays copied from the worldwide public holidays database.

 

Recurrence rules options

 

The 6 tabs are used to specify the following options (some of the above tabs may be disabled, depending on the type of recurrence selected in the first tab):

 

Type

The type of rule that the holiday follows. Is it fixed (the same date every year) ? Is it based on Easter ? Is it based on another calendar such as the Chinese calendar ? If you do not know what is the type of recurrence followed by a holiday, make sure you use the Holiday Rule Wizard.

Observance

Additionally, from the type recurrence options tab, you can specify the Observance of a holiday rule (for example, is it regional, religious, starts the evening before, ...).

Weekdays

Are there any special cases depending on the weekday on which the holiday occurs ? For example, if the holiday falls on a Sunday, should it be moved to the next Monday ?

Offset

Should a number of days (or weekdays) be added to the rules specified by the 2 options above. This is useful for holidays that last more than 1 day and which have a different name on each day (for example Hannukah). This is also useful for holidays that follow another holiday, such as Boxing Day and Christmas.

Duration

How many days does the holiday last ? This is often used for holidays of the Muslim and Chinese calendars.

Conflicts

Should something be done if a holiday occurs on the same date as another holiday ? This is used in a few special cases such as Mother's Day in France, but mainly to specify the behavior of days in lieu (additional holidays that are given if a holiday occurs on a weekend).

Validity

Are there any limits on the validity of the rules specified by the above options ? For example, Japan changed the way its holidays are calculated in 1999, so you may have a set of Japanese holidays with validity up to 1999, and another set of Japanese holidays with validity starting in 2000.

 

Additionally, there may be years when the rule for a holiday does not occur because of another special event. For example, in 2002, in the UK, the 50th anniversary of the coronation of Queen Elizabeth II replaced the Spring Bank holiday. In that case an exception to the Spring Bank holiday was specified, meaning that the rule applied every year except in 2002.
