What is Daylight Saving Time?

Twice a year, many countries adjust their clocks to make better use of daylight. This practice, known as Daylight Saving Time (DST), means we ‘spring forward’ an hour in March to mark the beginning of Daylight Saving Time and ‘fall back’ an hour in October to return to Standard Time.

It’s that time of year again: the clocks have fallen back by an hour. The change marks the end of Daylight Saving Time and a return to Standard Time, as well as a swap from lighter evenings to brighter mornings as winter approaches.
