    Some provinces have specific holidays, only those are included in the
    PROVINCES, because these provinces have different administrative status,
    which makes it difficult to enumerate.

    For religious holidays usually happening on Sundays (Easter, Pentecost),
    only the following Monday is considered a holiday.
