I've been using this notepad for 2.5 years and it's perfect. I'm very used to Mon-Sun planning from working in corporate worlds that follow this same practice, so I love that this calendar is laid out this way. Being able to start this calendar mid-year was the main reason I picked it up, and I still really enjoy filling in each month as I go. It also doesn't take up a lot of space on my desk, it looks beautiful, and it is always visible.
