The sale times are extremely confusing

It’s not just me who thinks this, right? It says some items are gonna be on sale literally right now, but they start on friday, but they don’t say ”friday (time)” they just say ”(time)” so i’d assume it’s today? But not, it’s supposed to start friday and the items aren’t available. But if the ones that have just the time listed start on friday, what about the items that actually say friday that happen the same time??? I’m genuinly worried i’m gonna miss some items because of the confusing times. Like, what am i supposed to think? Someone help, please.
