Hi Guys,

Is there any documentation on how to configure the default business calendar. We would like to configure it so that it does not count weekends or public holidays for timer events.

Regards

Brian

Hi Brian,

Set your own `org.flowable.engine.impl.cfg.ProcessEngineConfigurationImpl#businessCalendarManager` and replace `org.flowable.common.engine.impl.calendar.DueDateBusinessCalendar` with your implementation.  
See `org.flowable.engine.impl.cfg.ProcessEngineConfigurationImpl#initBusinessCalendarManager`

Regards  
Martin
