    For holidays that can be moved to a Monday if they fall on a Sunday, between 1984
    and 2013, the State Committee of Work and Social Security would determine if they
    would be moved to the Monday, or if they would stay on the Sunday, presumably
    depending on quotas. After 2013, they always move to Monday. I could not find any
    records of this, so I implemented this making it always go to the next Monday.
