I haven't really considered that much about it, but if I had to I always just imagined it was the next day.
Seeing as it was nighttime while Simba and Nala arrived at the Elephant Graveyard and while Mufasa talked to Simba afterwards, and it's obviously daytime while the whole stampede situation was going on.
I just assumed Scar 'got everything ready' but that night and then acted his plan out in the morning, because that's when the herd of wildebeests arrived, of course.
Scar does have a very intelligent mind, and it almost seemed like he had this idea prepared by the time the hyenas came back to his den. So I just figured it was the day after the Elephant Graveyard incident.
