Fall Started With Autumn Equinox at 10:49 A.M.

Summer was fun while it lasted, Springfield.

The season officially ended at 10:49 a.m. Saturday. That's the moment when the Autumnal Equinox occurs in the Eastern United States.

The Old Farmer's Almanac explains what's happening:

On the first day of fall—the autumnal equinox—day and night are each about 12 hours long (with the actual time of equal day and night, in the Northern Hemisphere, occurring a few days after the autumnal equinox). The Sun crosses the celestial equator going southward; it rises exactly due east and sets exactly due west.

Here are a few ideas to help you mark the day:

• Sun salutations: Philly Area Yoga is celebrating the fall equinox today from 6:30 to 8:30 p.m. Join them at 333 Morgan St. Phoenixville.

• Argue with a friend that Golden Delicious is the superior apple for pie: Here's a nice list for local apple picking options. (Save us a slice!)

• Get lost: Grab the car and hit the Delaware Art Museum. Today they have a special fall equinox program where you can walk the labrynth at 1 p.m. with no fee.
