This is a desk calendar that starts on a Sunday and allows you to check three months at once, making it easy to manage your schedule in the future. The three pages can be turned over separately: the left page (1, 4, 7, 10) for the month, the center page (2, 5, 8, 11) for the month, and the right page (3, 6, 9, 12) for the month. It is made of bagasse paper, which uses the fibers that are left over after squeezing sugarcane during the sugar manufacturing process.
