Gradually increase the amount you're saving each day to a pot of your choice. On 1st January, you'll save 1p. On 2nd January, you'll save 2p. This goes right up to £3.65 (or £3.66 😁) on the last day of the year! Feel free to jump in part way through the year, and see how far you get! The challenge resets automatically on January 1st every year.
