It's that time of year again. On March 28, Britons brought their clocks forward to usher in Summer Time, or as it's more commonly known, daylight saving time.
They aren't alone - about 70 countries around the world also still adopt daylight saving time.
British Summer Time begins at 01.00 GMT (Greenwich Mean Time) on the last Sunday of March and ends at 01.00 GMT on the last Sunday of October. For those who are (understandably) not sure as to when that is, it falls on October 31 this year.
The rationale behind it was that people like farmers, whose schedules are more likely to depend on daylight hours, will wake an hour earlier than they would have otherwise and thus begin and finish work routines earlier.
Adopting daylight saving time leaves them with an extra hour of daylight after work during warmer months of the year. At least, that's the theory.
And here's a fun fact for you: Hong Kong actually initiated daylight saving in 1941 as part of the war effort, and retained it until 1976.
So take this as an early reminder to turn your clocks back once daylight saving is over. See you in seven months.
