The Scots are very wise; they reserve January 2nd as a 'Hangover Day'. After the revelries of Hogmanay, and New Year's Day, they need another full day to recover. Nicola Sturgeon has the right idea.
I only noticed this important day whilst checking my on-line Calendar engagements. I also noticed that binge-drinking England has no such holiday; I wonder why? They probably need it more than the Scots!
