Where can I get a poster (image) of the year broken down into months and days to visualize events?

Question

Time Management

A couple of years ago, or maybe a year, on Habré or another resource, I saw a post in which the author described the poster for his author. The poster shows a year in the form of a pie chart, the year is divided into sectors - months. Months can be divided into segments - days.
The author told how he marked various events on such a poster for several years and how he finalized this poster over time. I don’t remember exactly what the author did professionally, but I remember that he spoke a lot at conferences and events and marked them on a poster (one of the examples of use).
Couldn't find this topic or poster in posts or bookmarks, just like Google. Comrades, help me find this poster, thanks.
