I often wondered where the Scots Hogmanay tradition came from, and why it was always the big festival of the year.
Ignorant me. The Calvinist, Puritan tradition lived long in Scotland. In England Cromwell's men had outraged the population by banning celebrations as Popish idolatry. But in Scotland, not celebrating Christmas was a token of virtue and difference from the slackers south of the Solway.
Christmas Day was a normal working day in Scotland until 1958.
Nowadays Scots still don't celebrate Christ's birthday. But they buy presents and get drunk just like the English do.
