It isn’t stated explicitly, but editing choices made in the first “John Wick” film suggest that the entirety of the narrative takes place in just five days, assuming John’s dog, Daisy, is killed the day after he receives her. Though some online speculate that a few days pass between the funeral and Iosef Tarasov’s attack, it appears in the film as though John’s first trip to buy dog food and Daisy’s death happen within 24 hours of each other.
Given John’s inhuman focus (as well as his identical wardrobe), it’s probably safe to say that the time jump between “John Wick” and “John Wick: Chapter 2” is between one day and one week — enough time for John to “heal” (considering John heals way quicker than the average widower) and for Aurelio (John Leguizamo) to track down the car John borrows in the film’s opening moments. In all, “Chapter 2” takes place over eight days.
