The minute I hit post on this — it’s the Autumn Equinox*. That’s when the days become shorter than the nights and officially marks the beginning of fall. They’ll keep on getting shorter until the Winter Solstice at the end of December, when winter begins and the days start getting longer again.
And, perhaps for the last time ever, our 4.5-star rated iOS app Sol: Sun Clock is free in the App Store for 24 hours!
* (or Spring Equinox for those of you below the Equator when the days become longer than the nights.)
