Hi,

I'm looking for insight on the difficulty that I've experienced,

I want to add a holiday to the operating schedule. It is a repeating holiday, but when I check the date, it shifts to different days. (Some in the list will shift to Month next year)

I've tried custom rule, FREQ=YEARLY;WKST=MO;BYMONTH=3;INTERVAL=1;BYDAY=MO;BYSETPOS=-1 but no luck since i was only basing on the Genesys article. Seems i can't get the right order or combination in the custom rule.

Here are the examples of the said holidays:
Karfreitag             3-29-2024      4-18-2025    4-03-2026
Ostermontag       4-01-2024      4-21-2025    4-06-2026
Auffahrt                5-09-2024      5-29-2025    5-14-2026
Pfingstmontag     5-20-2024      6-09-2025    5-25-2026

Do we have a way to create holiday schedule with a different day/month for that just specific holiday for the occurrence? Thanks!

Hey Jason, 

The holidays you've listed are all related to Easter, which itself does not have a fixed date and is calculated as the first Sunday after the first full moon occurring on or after the equinox.

Given these limitations, a programmatic solution might be necessary:

1. Karfreitag (Good Friday): Occurs two days before Easter Sunday.

   • There's no direct way to create a recurrence rule for Good Friday in RFC 5545 due to its dependence on Easter's date.

2. Ostermontag (Easter Monday): Occurs the day after Easter Sunday.

   • Similarly, a direct recurrence rule for Easter Monday cannot be created with RFC 5545.

3. Auffahrt (Ascension Day): Occurs 39 days after Easter Sunday.

   • This also cannot be directly represented in RFC 5545.

4. Pfingstmontag (Whit Monday): Occurs the day after Pentecost, which is 50 days after Easter.

   • Like the others, this cannot be directly represented.

Because these holidays are based on Easter, which moves annually, and their occurrence is not fixed to a specific date but rather a specific number of days before or after Easter, the RFC 5545 standard does not offer a direct method to encode them as recurring events.

Hey Lawrence,

Thank you for the insight! Really appreciate it! So i need to set up these holidays every year since they are not fixed date, correct? Thanks!

Hey Jason, 

Yeah, that's right - You'll need to create one-off instances for each of those holidays. Things like Christmas, and other PH that fall on say First Friday of each October etc are easy to use a recurring rule for. These are a bit more nuanced.
