Today's Hours by Planet in Glasgow
Planetary Hours in Glasgow Through 2026
So far from the equator, the swing is large. A daytime hour in Glasgow shrinks to 35 minutes around Dec 21 and stretches to 88 around Jun 21, nearly 2.5 times as long.
Clocks in Glasgow go forward an hour on Mar 29 and back on Oct 25. The planetary hours follow the Sun, so the hours themselves don't move; only their clock times jump by an hour overnight.
The shortest day is not the darkest at both ends: Glasgow's earliest sunset comes 11 days before it, on Dec 10, and its latest sunrise 5 days after it, on Dec 26, because solar noon drifts through the year.
