Should calligraphy be written in lunar or solar calendar?

It depends on whether it is brush calligraphy or hard pen calligraphy.

For brush calligraphy, you can write:

Xin Chou Middle East/John XX Books

Brush calligraphy generally adopts traditional format. Signature can have a deposit. Only the next paragraph is commonly used, and the format is: time (generally not Gregorian calendar)+(%place)+author+(respect) book, such as "Xin Chou Xia Yue respects the book in Gufengtang XX". In traditional calligraphy, dates are marked by years, and months are marked by lunar calendar, not specific to a certain day.

Hard-pen calligraphy, if arranged horizontally, can be in modern format: 202 1 year1February, X, XXX book. If it is vertical, it should also be in the traditional format.
