It was November 12th at 3 PM.
I rewatched this part of BB...Saul is not seen at all in "Ozymandias", it was two episodes before that where Jesse mangles his face, and in the following episode Saul talks to Walt about what happened and how Jesse is a problem that needs to be taken care of. Then later he finds Walt at the carwash, and tells him the Huell is missing...so we don't know exactly what triggers Saul to get out of Dodge, but my guess is that Jesse dropped Saul's name to Hank and Gomie, and he got a call from the DEA....
I think Jimmy does what he always does, finds a way to use an opportunity. Seeing Howard suffer emotionally for Chuck's death means that the 'suffering' is happening, and it's not on Jimmy to deal with....he can move on.
And with Kim....the self-sabotage is becoming quite apparent, she obviously just wants to feel like she's doing something 'good', and doesn't quite know what that looks like....my feeling is that she sees Jimmy trying to be 'good', and thinking that once he becomes a lawyer again, if she's at his level (doing PD work rather than the high-profile stuff) then she can be 'good' with him. I think she also has the feeling of "If I had just been there with Jimmy when he was younger, if I had been able to set him straight and just help him a bit...maybe he would be a better person and feel better about himself....I care so much for him and I want him to feel better....he's been through so much and obviously he feels so terrible about his brother's death (which that bastard Howard is responsible for) and is just trying to be strong and move on....maybe I can make up for it by helping others like him instead of just making a bank richer...." Something like that.
One thing I just realized - it doesn't make sense for Kim to be lawyer that Francesca calls. Francesca obviously knows Kim, she used to work for Kim for crying out loud! And she certainly wouldn't have to tell Kim that "Jimmy sent me". The only - ONLY - way it makes sense is if Kim is now working for another firm somewhere as a criminal lawyer, and saying "Jimmy sent me" is some sort of code that gets someone sent over to her.
With regards to the call on November 12th - Jimmy is actually asking Francesca to be at a certain place at 3 PM. If anything she is going to *receive* a call, not make it. I think it's likely from the dialogue that Jimmy will be calling her on a burner phone he has provided for her, or she will have to get something from someone to get to him somehow. What the call might be about is still quite up in the air, but I am quite sure that it's to give her his new address so that she can get something to him, or maybe just news about what happened to his practice and his clients, and to make sure nothing follows him to Omaha
