Hi, Does anyone know if there is a plugin or function that can be use

There's no plug-in to analyze a calendar but:

1. There are date and time functions that take a calendar name such as calisworkday() which will determine if the passed datetime is a working day or not
2. You can also use the API to analyze your calendars:


WorkingCalendar[] calendars = (WorkingCalendar[]) calendarService.getCalendarsPaging(0,
Constants.COUNT_ALL, TaskSummary.SORT_BY_NAME, Constants.SORT_ORDER_ASCENDING).getResults();

for (WorkingCalendar workingCalendarItem : calendars) {

//Use any method over workingCalendarItem that may fit your requirements from the ones available at forum.appian.com/.../WorkingCalendar.html

}

Thanks Eduardo for the information.
