Montréal: looks like it’ll be *just* clear enough to see the thin Crescent Moon

Look low in the Western sky between 8:00-8:45 PM

Today is the Spring Equinox. You made it!

The entire Earth gets the same amount of daylight – about 12 hours. A few other neat things:

☀️ The Sun rises exactly East

🌅 The Sun sets exactly West

🌎 The Sun is directly above the Equator at Solar Noon (if you were there, you'd see no shadows!)
