Holidays: can only be taken in blocks of 7 days. Always start on a Saturday. You get wrap days (days supposedly free of duty) either before or after the 7 days. Before, then you get 3 wrap days prior to the Saturday OR 4 days after i.e. you only get one set of wrap days on a 7 day block. If you manage to get 14 days off, then you'll get 3 wrap days at the beginning and 4 off at the end, unless you bid otherwise.
