I'm submitting my PhD in 33 days. The whole thing is now essentially written. There are some references to chase up, some bits of syntax to straighten out, a contents page to create, but the body of the work is pretty much all there. I've got a full month now to tweak it as far as possible, make sure the arguments are tight and that I'm happy releasing it to my examiners.
It's been a bit of a slog, but it'll be in within the three year mark and, hopefully, it'll be a good thesis. One can never tell, of course, until the viva, but I hope that I'll be able to hand it in with a smile as well as a sigh of relief.
