Okay I've heard different things from different people. when does the third trimester start?

thank you @proudtobeamom I didn't wanna sound stupid but someone also told me 26 but I have the ovia app too and it still said 2nd trimester. this is my first baby so I'm kind clueless.
well I know it's not 36 or 37. that's almost the end of a pregnancy. I'm at 27 weeks now so next week I should be in my third right? @proudtobeamom
I think 36 but I'm not sure or 37 .. I try to google I get diff answer ..
