I'm actually sick and tired of online calendars. For all of my life, I've been using Google Calendar as the main tool to arrange my work. And, you know, though it's always been messy for me, I would still go on using it. So I decided to try a printed
november calendar. I found the same one but for 2021 in my table. And personally, the printed version is much more comfortable for me. When you write down your daily tasks, your brain fixes it twice. So, IMO printed calendar has increased my productivity.
