Night and Day is a Bear in the Big Blue House storybook published in 2000.

Bear describes a situation and then asks readers to figure out if it's night or day. The book comes with a spinner featuring Ray on one side and Luna on the other. It instructs the reader to turn the spinner to match what's on the page. Scenes include waking up in the morning, a nighttime starry sky, having breakfast, playing at the Otter Pond and sleeping at night.
