Customize business calendar for holidays

Hi, I would like to know if is there some detailed example about the customization of the business calendar to include personalized holidays?

At this moment there is only one article in the forum How to configure the business calendar
but it isn’t clear enough.

No, there isn’t much documentation available about that topic yet. The interface you need to implement is here: https://github.com/flowable/flowable-engine/blob/master/modules/flowable-engine-common/src/main/java/org/flowable/common/engine/impl/calendar/BusinessCalendar.java. The implementation then needs to be injected into the engine configuration. Also note that timer event definition in the BPMN needs to get a calendarName to resolve to it: https://github.com/flowable/flowable-engine/blob/master/modules/flowable-engine/src/main/java/org/flowable/engine/impl/util/TimerUtil.java#L96
