Why is the 29th of the twelfth lunar month the "last day"?

20 19 The 29th of the twelfth lunar month is the "last day", which is a saying that solar terms alternate in the China lunar calendar. The ancients were afraid of exhaustion and thought it was unlucky, so according to the old calendar, there were many taboos on this day, including posting couplets.

Absolute day is just a name of solar terms, and it is not as terrible as imagined. Absolute day doesn't mean you can't post Spring Festival couplets.

As usual, most people put up Spring Festival couplets on their first day in beginning of spring, that is, New Year's Eve. If there is no New Year's Eve this year, people will choose to put up couplets on the 29th of the twelfth lunar month, especially for some businessmen. Posting Spring Festival couplets in advance is a time-saving practice, so there are not so many taboos. As long as you are honest and happy, there is no absolute statement!
