The US also has Daylight Savings Time in the summer. In the spring, we set out clicks ahead on hour, which gives an extra hour of daylight on the evening (and less in the morning). In the fall, we set out clocks back one hour, losing that extra hour of daylight at the end of the day.
We don’t gain or lose any daylight. We just change our schedules so the “extra” hour of daylight is available when more of us are awake. In the winter, there isn’t any spare daylight to shift around, so the clocks shift back.
