Daylight saving time doesn't apply to the winter though.

Winter time is standard time, and DST is in effect during the summer months to better make use of the extra light available during summer by winding clocks an hour forward. The idea being that you get an extra hour of sun in the afternoon.

Yes, sorry, moving back to standard time provides a boost in winter.

Both clock adjustments provide different benefits, which is why we do both, to get both benefits. Abolishing DST means you pick one of the two.

The idea was actually to save power by extending the part of the day that had sunlight.
