The Mishnah taught that amongst their festivals are the (memorial of the) coronation day (and the birthday of the king.). A source for their celebration of the king's birthday is the pasuk (Bereishis 40:20), "And it was on the third day, the birthday of Paroh".

The Mishnah taught: The king's birthday and day of death.

Question: Until now, we have been discussing a community. But as for the law of the following Mishnah that the festival on the day that he shaves his beard and his Bluris (crest of hair on the top of his head, running from his forehead back to his neck), it is a private festival for that particular idolater.

Question: The Mishnah taught that any death of such an important person that involves burning his clothes and possessions is considered a festival of idolatry. But doesn't the pasuk state (Yirmiyah 34:5), "You shall die in peace and with the burnings of your forefathers", which shows that burnings were the custom of Jewish kings as well?

Answer: Rather, the Mishnah means that any death that involves smoking (i.e. burning up incense to idols) and burning (of the person's possessions) is a festival of idolatry.

(Mishnah): The day on which he shaves his beard and his Bluris, the day that he was saved from drowning at sea, the day that he left prison and if an idolater made a banquet for his son, in all of these cases, only that man and only that day is prohibited.

(Gemara): What does the Mishnah mean by "only that day"? Only the day it happened or every year on the same day of the year?

Question (Beraisa): The day of his shaving and the shaving of his son are prohibited. (It is understandable if it is observed the same day every year, so it is possible that his son shaved on the same day as his shaving, many years later. But if it is observed only the first year, how could his son have shaved on the same day as him?)

Answer: They were shaved at the same time.

Question (Beraisa): His wedding day and his son's wedding day are prohibited. (Asking as before, that if it observed only the first year, how could his son have married on the same day as him?)

Answer: They both shaved and then married on the same day.

Question (Beraisa): His birthday and his son's birthday are prohibited. Could you say here that they were born on the very same day? (How could they be father and son?!)

Answer: When he didn't manage to celebrate the festival until his son was born and he then celebrated both occasions. (Note: The Gemara does not answer the original question.)
