these types of logic tests should be a requirement for comp tbh

this is isn't really difficult guys, like the only only issue is people failing to interpret that Albert just outed that arbitrarily
- albert says words - the fact that he knows immediately that it can't be bernard means he doesn't have a month with a unique date so you can rule out may and june - then when bernard says he figured it out that means he must have one out of 15, 16, 17 as the 14's are eliminated due to not being unique - then when albert figures it out we know it's june 16 and not the two august dates since he wouldn't be able to work it out in that case.
As Bernard knows the day, yet doesn't knows the date at first, that implies three dates are impossible: June 18 and May 19. Albert knew that he didn't knew it at first, so in reality, Albert would be contemplating those possibilities:
May 15 May 16 June 17 July 14 July 16 August 14 August 15 August 17
Albert still doesn't knows, so it can't be June 17.
May 15 May 16 July 14 July 16 August 14 August 15 August 17
Albert claims he doesn't know the date, and that he took in consideration that Bernard didn't know it either when ruling out the possibilities. From this point onwards, both Bernard and Albert should be visualizing the same "realm of options".
Bernard immediately finds Cheryl's birthday; That's only possible if the number he knew was the only one within the realm of possibilities: In this case, 17. As Albert is visualizing the same realm of possibilities, he is also aware of that fact.
Cheryl's birthday is in August 17th.
Now I'll google it to check if I am right.
... All right, looks like I got it wrong. Damn, I was so confident.
thats what i ended up doing, but i figured it had to be something like that, and then look at which ones had similarities. like the furthest i got was how 18/19 were unique, so neither of them could be right. other than that, i was lost
