Every spring we set our clocks one hour forward. Every fall we move them one hour back. It’s a strange ritual when you think about it, so why do we do it? Join Molly and co-host Ava as they explore the seasons and why days are shorter in the winter and longer in the summer. We’ll hear about the history of Day Light Saving and play a game. And it’s always time for a Mystery Sound! So set an alarm so you don’t forget to tune in to this episode!
