A year consists of 365 days. I don’t believe that anyone can instantly answer how many numerals are needed to represent the 365 days. The answer is 622. The calendar was a project designing 622 different numerals based on a different idea for each month of the year. In seven years, I designed 4356 variations of axonometric three-dimensional numerals based on 84 different ideas. Except for some, most were drawn manually with a ruling pen.
