:relfileprefix: ../../../
:mrdocs:

Mark the specified `date` as a holiday (i.e., a non‐business day) in this calendar and add the specified `holidayCode` (if not already present) to the set of codes associated with `date`, if `date` is within the valid range of this calendar. Return 0 if `date` is in range, and a non‐zero value otherwise. If `holidayCode` is already a code for `date`, or if `date` is not in the valid range, this method has no effect. See {Iterator Invalidation} for information regarding which iterators are affected by the use of this method. Note that this method may be called repeatedly with the same value for `date` to build up a set of holiday codes for that date.
