Movable type printing calendar

It is better to teach a man to fish than to give him a fish. Inspired by one of China's four great inventions, movable type printing: by making a separate model for each date in the calendar, you can arrange your own calendar for each month.
Each date module is designed with a positive engraved reverse text mold and a negative engraved positive text mold on the front and back respectively, which can be stamped and printed out of the calendar or used directly as a calendar.
Not only for 2024, but a perpetual calendar!

The front and back of each date module are designed into a male and negative inverted text mold and a negative engraved positive text mold, which can be stamped and printed out of the calendar or used directly as a calendar.
Not only 2024, but also a perpetual calendar!
