+The wxDateTimeHolidayAuthority-derived classes help determine whether a
+given date is a holiday and are used by all functions working with "work days".
+In this context, a holiday is an event which results in a day off from work.
+
+Multiple holiday authorities can be combined by passing them to
+wxDateTimeHolidayAuthority::AddAuthority(), and a date can be verified as a holiday
+by calling wxDateTimeHolidayAuthority::IsHoliday().
+
+Holiday authorities are available for weekends (loaded by default) and
+Catholic/Christian holy days of obligation.
+Custom holiday authorities can also be created by deriving from wxDateTimeHolidayAuthority
+and defining DoIsHoliday() and DoGetHolidaysInRange().
