Today's Hours by Planet in Montréal
Planetary Hours in Montréal Through 2026
So far from the equator, the swing is large. A daytime hour in Montréal shrinks to 44 minutes around Dec 21 and stretches to 79 around Jun 21, nearly 1.8 times as long.
Clocks in Montréal go forward an hour on Mar 8 and back on Nov 1. 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: Montréal's earliest sunset comes 17 days before it, on Dec 4, and its latest sunrise 11 days after it, on Jan 1, because solar noon drifts through the year.
