If you mean April Fool's Day on the 1st of April. Then yes, this day is celebrated on the forum every year. For example, today Theymos came up with a joke with merits. You can read about it in his thread:

By the way, I forgot that today is the 1st of April and fell for this prank. I think this is the best joke ever from Theymos.
I think one thing is, for most of us who are already familiar with such happenings in the 1st day of every April, it's wouldn't look so much like fun for even if we fall for the April fool's prank, it shouldnt take us more than (at most) 5 seconds to realized that it's just an April fool's prank, just like I did fall for this one today and in less than 2 seconds, I occurred to me that today is the 1st of April and that the thing with merits being reduced on every post I made is as a result of an April fool's prank.
I remember the year, either 2020, 2021 or 2022, this was the year I experienced my first April fool's prank on this forum, I tell you, the experience was not funny, for over an hour or so, I havent realized it was a prank, I was going to contact some prominent users who I believe to be close to Theymos to help me look into the issue with my account, but after over an hour searching and reading posts in the forum (I was an Altcoiner and wasn't familiar with the meta or bitcoin board back then, I only posted in Altcoins boards and it's sub-board) I finally discovered it was an April fool's prank, the feeling was out of this world I tell you 🤣.
By the way, feeling like putting up some bets on bitcoin price on freebitco for the month of April, how are you guys expecting the price of bitcoin to perform this month.?
