Explanation
A handy memory tip for Daylight Saving Time (DST). This memory aid reminds us how to adjust the clock. In the fall (autumn), the clock will be set back an hour. In the spring, it will jump ahead one hour. William Willett, in the "Waste of Daylight," published in 1907, first seriously proposed the concept of DST; but he was unable to get the British government to adopt it, despite considerable lobbying.
Alternative mnemonics
- 3+ 10-
- March (3) is when the clocks spring forward (+). This works for the UK and EU, where DST ends in October (10), but not for the US and Canada: since 2007 they've ended DST on the first Sunday of November instead, so "3+ 11-" would be the accurate version there.
