Press-type desk calendar

I designed a special desk calendar that doesn't require any extra parts. All you need to do is assemble all the printed parts, and it can be used. Although it might be a bit stiff, a slight push on the buttons will allow it to continue working.This calendar allows for the free arrangement of dates, months, and days of the week, accommodating different date formats used in various countries. Sorry, I forgot to upload the version for this week. I have now added the file. Thank you all for the reminder.
