Help! Is "Day 18" Eighteen Completed Days?

[JillsChicks]

I thought I was on day 18 and ready to stop turning my eggs. But now I'm wondering if "day 18" means that I've completed 18 days. My Day 1 was started when I set the eggs in the incubator, not after having been in the incubator for 24 hours. Which do I measure by? Do I stop turning now or tomorrow morning?!

According to what I picked up here -I asked almost the same question a while back- the day you set is day 0, day 1 is 24 hours after you set.

Thanks, Tiffany, for your reply. How agonizing to think that I'm a day farther behind... But at least I know when to properly start raising the humidity and stop turning those eggs. I would hate to have chicks with unabsorbed yolks because I upped the humidity too soon! Ann
