The day-age view isn’t the usual way of doing old-earth creationism nowadays, though. There are so many more options than just lining each day up with some particular period of time, and the probable way to put 1:1-2:3 and the rest of ch.2 together (if you’re going to do that, and while I know you don’t care, I would prefer to try) is to take the chronological sequence of 1:1-2:3 to be inexact but the events of the rest of ch.2 to be at least chronologically in order, whatever else might be true of them. If ch.1 is arranged sort of half-poetically, as I think most scholars now think, and it doesn’t go chronologically anyway, then there’s no reason for each day to be one chronological period, with the next following it. That allows for plenty of time. Even among those who don’t accept macro-evolution to the point of speciation and common ancestry with animals, there’s room for doing this without doing the day-age thing.
