A calendar without Mondays

Another year-end is coming, and it's time to change the calendar.

My grandfather likes the old-fashioned calendar books.

You know, those printed on thin paper, where you tear off a page every day - the old-style calendar books.

Next to the date, there are lunar calendar, royal calendar, and perpetual calendar.

On the back are recipes, common sense of daily life, and old auspicious words.

This kind of calendar book is not common now.

My grandfather likes this rare old calendar.

He always remembers to call and urge me to get one at the end of each year.

Therefore, I also pay special attention to the calendar.
