what time will the sanrio collab end on the 23rd?

i’ll be out of town this weekend and back monday afternoon so i was wondering what time collabs usually end on the last day? online i saw something saying 2pm est is typical but i wanted to double check to see if i should go ahead and just buy them today. i was gonna wait until i got more coins from the battle pass but i don’t think i have the time monday 😭
