How does twenty-eight lodging correspond to the date?

Twenty-eight lodgers take turns keeping diaries, with one night representing one day, twenty-eight lodgers representing twenty-eight, and so on.

The 28th is a cycle, which happens to take turns around. So, according to the rhyme below, you can check whether the twenty-eight nights printed on the almanac are correct, just look at the day of the week on that star (the corresponding relationship will never change).
