Calendars come in all sorts of forms, from the purely functional apps on our smartphones to the propped-up desktop ones that are mostly just a means of delivering a new Far Side joke every day. The Units of Measure Calendar Poster, as its name suggests, isn’t the most straightforward one to categorize. Or even one that’s easy to recognize as a calendar at all.

It doesn’t leave any room for you to jot down appointments, though it does include all 365 days, which you can notch off one by one. Mostly, it’s just an exquisite graphical compilation of 12 different units of measurement, a tightly packed collection of diagrams and conversion tables and other neat looking things of the sort.
