Something's going on outside. Is that...sunlight? Could it be? At this hour?

Yes, I'm thrilled to report that things are verifiably brighter, because today marks the Vernal Equinox. This springtime milestone marks one of two times a year when night lasts approximately the same amount of time as day (as BBC notes, "equinox" means "equal night" in Latin). It's also mercifully warmish, with the high at 52 degrees and the low at 41 tonight.

That means it's time to emerge from our dim apartments and fluorescent-lit workplaces and be out in the daylight, which will last until approximately 7:06 p.m.! And don't fret when night falls, because that's when the supermoon comes in (Vox notes that this means a bigger and brighter moon). It marks the first time since March 2000 that a full moon has fallen on the same day as the Spring Equinox, and it's also the last supermoon of the year.

This one is called a Super Worm Moon, so named because it's the time when earthworms start to emerge once again from once-frozen dirt, according to National Geographic.

This day is historically surrounded in lore. One myth holds that at a certain time today (5:55 p.m., to be precise) you can place an egg on the ground and it will stay intact. Park Slope's self-professed "Urban Shaman" Mama Donna will be holding the 44th iteration of her annual egg-balancing celebration at Grand Army Plaza's Bailey Fountain this evening. So if that's your bag, grab some eggs and head over.

And if you don't catch a good glimpse of the moon, this webcast of the supermoon in Europe is pretty rad.
