How about the thirteenth day of the first month?

According to the old custom, Pepsi Taboo Day is called "Yang Gong Taboo Day" and "Thirteen Taboos in Yang Gong" from the 13th day of the first lunar month, and then two days in advance every month. This biography was written by Yang Junsong, a geomantic master in the Tang Dynasty. These thirteen "taboo days" are 1 month 13, February 1 day, March 9, April 7, May 5, June 3, July1day, July 29, and July 29. So the thirteenth day of the first month is not suitable for going out.

There are some bad opinions about New Year's Day 13. They think this is a very unlucky day, so many things can't be done on this day. Things like getting married and moving are not suitable for this day. However, there is no scientific basis for these, so don't blindly believe them.
