[@Dusksong] Good luck with the exam!

[@Balthazar007] So, when should the eggs hatch? It's been a few days, so I'm thinking Cici could get her kitten in the morning if that's ok.

All eggs will hatch on the same day of the month that you placed it in your party, one month later (IRL). (E.g. placed in party November 3rd; hatches December 3rd.)

This roughly translates to 12 hours IC. Since we have done a time skip though, you can hatch whenever you like. 

Also, two changes to keep in mind. One, from now on, eggs are only available through daycare breeding. Two, mark your hatched Pokemon after they hatch. Hatched Pokemon level up at a double rate (besides rare candy).
