First: Open an EXCEL table and make a chart.
Second, find the corresponding almanac on the Internet and input the form according to the content.
Third: you can leave blank according to your own needs and enter some important historical events, especially those with babies at home. Desk calendar is an ideal carrier of popular science knowledge. I have written some events about scientists or great men in history.
Fourth: make a cover.
Fifthly, it will be converted into PDF after production, which will be printed by relevant printing graphic companies, and it will be a great success. After printing, my baby and I are very happy and have a sense of accomplishment.
Below is my own desk calendar.
