Celestially speaking, this will be a month of transition.

Northern skywatchers will be switching to Daylight or Summer time — on March 13th in the U.S. and Canada but two weeks later across Europe.

A second transition comes on March 20th at 7:21 p.m. Eastern Daylight Time, when Earth reaches one of the two equinox points in its year-long orbit. This signals the beginning of northern spring, astronomically speaking, and autumn south of the equator.

Low in the west, Jupiter slides lower into the twilight glow week after week, and by month’s end it’ll be too low to spot by eye. Before it goes, however, the King of Planets will pair up with elusive Mercury to put on a pretty celestial dance in the early-evening sky. Meanwhile, Saturn rises in mid-evening as it readies for a leisurely cruise across the summertime sky.
