Spin the “Weeks” wheel — with slices for every day of the week (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday — plus a wildcard “All the weeks”) — to randomly pick which day things get done, or to decide when to schedule an event, challenge, or task. As a fun fact: our seven‑day week goes back thousands of years — ancient civilizations like the Babylonians already used a 7‑day cycle based on lunar phases.
