If your country uses Daylight Saving Time (DST), you have to change your clocks twice a year.
Set your clocks forward 1 hour in the spring at the start of DST (Daylight Saving Time), and 1 hour back in the fall when DST ends. In North America the word “fall” is used to denote the season, while other English-speaking countries usually call it autumn. “Spring Forward – Fall Back” is therefore a phrase most often heard in the USA and Canada.
Records show that the phrase “spring forward, fall back” has been in use at least as far back as the early 20th century. It is the practice of advancing clocks during summer months so that evening daylight lasts longer, while sacrificing normal sunrise times.
