Every 210,000 blocks, the block reward for the miner is halved. A block is found about every 10 minutes, from this you can roughly calculate when the halving takes place. As of now it is less than 1 year. There are different countdowns, but April 2024 is likely. The last halving was in May 2020. The block reward was then halved from 12.5 to 6.25 Bitcoin. The upcoming reward will then be reduced from 6.25 to 3.125 bitcoin.
After reading through all these, what exactly are you trying to drive out from all you've said, because there's nothing new here than tothology, just like teaching an average adult what food is when it's something everyone has been used to, we already know about halving, but what more do we need to be informed of different from what we already know.
An idea for a new guessing game: guess the date and time of the first block of the halving.
How can we, is this a riddle or game, all we know is that between March and May of next year we are going to experience another halving to mark the 2024 experience after the last we had in 2020
