xmas day and constitution day are not formal holidays in denmark
The holiday the day after New Year's Day in Scotland is more commonly referred to as "2nd January". It also behaves similarly to Boxing Day when it falls on a weekend.

The St Andrew's Day Bank Holiday (Scotland) Act 2007 added St Andrew's Day (30 November), or the following Monday should November 30 fall on a weekend to the schedule of bank holidays in Scotland. Not widely observed as the St Andrew's Day holiday can only be substituted for an existing local holiday from another date in the year, so marking as informal.
