LORELAI: Hey Sookie. Is there any coffee left? I had a really lousy night.
SOOKIE: Oh sorry. Ya know, I’ve been so busy I didn’t even think about it.
This scene takes place on the day following the night where Lorelai had a fight with Emily – oddly, they both take place on Saturdays. We know this because the fight took place the day after Friday Night Dinner, and the engagement party is also on a Saturday. But instead of those things being a week apart, they happen within 24 hours of each other.
