Neo Has A Question - Tumblr Posts

Can someone like. Explain the whole it’s sun wukongs birthday thing to me. Like I’ve been researching and the mytho does say “it’s celebrated the 16th day of the 8th lunar month” buttttt is that just august 16? Or September tenth (when mid-autumn festival takes place.) if using the Chinese (2022) lunar calendar, also the people in Tik tok keep saying it’s both 15 and 16 and do not back up their claims please help. Like genuinely. ^_^..
