Is it appropriate to see a patient on the fifteenth day of the first month?

Whether you can visit the patient on the fifteenth day of the first month depends on the specific situation.

If the fifteenth day of the first month is not the day when people die, you can visit patients on the fifteenth day of the first month, otherwise you can't visit patients.

When is the Day of the Dead? According to Jade Sagger, every day in Rizhu Jiayin, Mao Yi, Jimao, Renyin, Renwu and Wu Geng is a "day of death", which is not good for visitors themselves, so it is forbidden to visit patients.

That is to say, from the perspective of the Gregorian calendar, if the 15th day of the first month is not the day of Jiayin, Yi Mao, Jimao, Renyin, Renwu and Gengwu, you can visit patients.
