January

HB calendar for January of 1978 featuring Captain Caveman and the Teen Angels.

January is the first month of the year.

Scooby-Doo

• In the first Shaggy & Scooby-Doo Get a Clue! episode, "Shags to Riches," Shaggy had a calendar in his apartment that said January, and since the last episode, "Uncle Albert Alert," was set an entire year later, this would presumably mean that episode is set in January, too.
