Most nations don’t observe daylight saving time. And for people who do — largely in Europe and North America — the date of the clock change varies, partly due to how time-related legal guidelines had been developed in distinction locations.
In nations that observe the observe, clocks are set ahead one hour from commonplace time in March to benefit from elevated summer season daytime within the northern hemisphere.
Clocks “fall again” once more within the autumn to plain time.
