In the Tsubasa Cat arc, I remember Hachikuji saying that she saw Shinobu at Mister Donuts and she ran away.
When did Hachikuji meet Shinobu? As far as I remember, Hachikuji never met her, except in Kabukimonogatari.

We don't see that happening but before the fight with Hanekawa, Araragi checks Mister Donut since Mayoi says she saw her in there. Because of this Araragi goes there and cant find Shinobu regardless but it is safe to assume that Shinobu hides in Araragi's shadow when he enters and the events of last arc happens.
I can also prove this with another arc in Monogatari Second Season. Spoilers!
In Mayoi Jiangshi arc Mayoi was never able to see Shinobu thus causing the death of Araragi since she, Shinobu, wasn't able to sneak Araragi's shadow.
Since we know this fact we can say it happened on the same day.
