Take a crash course in astronomy!
The Bad Astronomer, aka Phil Plait (who is actually a Good Astronomer) invites you to check out his new series on understanding astronomy. These videos are short and engaging lectures , each of which focuses on one particular topic in astronomy. As of February 2, there are three videos with many more on the way. Both newbies and veterans of astronomy will find something to like in these videos, and you may earn something new!

Check out the cycles of the planets, Moon, and Sun. The sky is a calendar, and in fact humans first used their observations of the cycles in the sky to identify the star of seasons, schedule holidays, maintain agriculture, and more.
