I refused to look up the answer to the Silent Hill 2 hospital keypad

I went to sleep and thought about it all day

I thought about crazy shit like Z is the 26th letter, X is 24, T is 20th but there's no "0" on the keypad

I thought it must be some kind of math with the current month, and tried to see if there was anything that said what month it was in Silent Hill

Spoiler: I tried doing a "T" shape but it didn't work, I eventually thought it must it must be a lower case T cross, I tried every combination over lowercase "+", I thought, maybe it's the next month already, so I tried different letters, I tried N like 20 times convinced it must be N, I tried S like a backwards Z then just every flip of Z N S etc. possible... It was just a "T" shape but in a combination I didn't try
