Introduction: The Day I Lost a Bet Because of a Calendar
Last Christmas Eve, my 9-year-old nephew asked, “What has hands but can’t clap?” I smugly answered “A clock.” He grinned and said, “Wrong! A calendar — it has hands (dates) too!” The whole family roared. I owed him ice cream for a month.
That moment reminded me why calendar riddles are pure magic: they’re simple enough for kids, sneaky enough for adults, and they make you look at something you see every day in a completely new way.
If you love this kind of brain-teasing fun all year round, you’ll also enjoy our collections of December riddles for winter nights, November riddles for cozy autumn evenings, and September riddles to kick off the school year.
