fall back : time to reset our clocks

|

It's gonna be the American first to reset the clocks in November instead of October. The time of day is "falling back" an hour this weekend meaning, we can get an extra hour of sleep.

The change officially takes place at 2 a.m. Sunday, Nov. 4, but most Americans tend to turn clocks back an hour before going to bed Saturday night. The time switch marks the end to daylight-saving time, which started way back on the second Sunday of March. This year marks a slight shift in routine instead of dropping daylight-saving time during the last weekend in October, the changeover occurs on the first weekend in November.

The idea behind daylight-saving time — or summer time, as it's known in other parts of the world — is to use the extended daylight hours during the warmest part of the year to best advantage. Timekeepers shift some of that extra sun time from the early morning (when timekeepers need their shut-eye) to the evening (when they play softball).

The shift reduces the need for lighting during the evening, and that's why daylight-saving time is considered an energy-saver — that is, as long as there is morning sunlight to spare. Now that the days are shorter, the daylight-saving advantage has largely dissipated. With the clocks turned back, it will be lighter (or at least less dark) in the morning, but darkness will fall earlier in the evening.

Not everybody goes along with the daylight-saving plan. Arizona and Hawaii, for example, stay on standard time all year round. Each state or country comes up with its own schedule for the switch, and that schedule may be subject to change.
Around the world, Canada and the members of the European Union operate similar summer-time shifts. And yes, some countries in the Southern Hemisphere move their clocks forward an hour at this time of year, in time for the coming summer there.
