According to an old Scottish rhyme, the last three days in March were “borrowed” from April, in return for which March promised to destroy three young sheep. Other references go back even farther. Both an ancient calendar of the Church of Rome and a 1548 book known as The Complaynt of Scotland allude to the days at the end of March as being more like winter than spring. Whatever their origin, it seems likely that the wet, windy weather that so often comes at the end of March gave rise to the notion that this month had to “borrow” some additional time. Discuss
