Just curious...is it too late for a snack before dinner?

Well, that depends. Where are you? In Nova Scotia it might be too late and in Vancouver it might be too early.
I have breakfast before 6:30, lunch about 12:30 and dinner at 7 ET. Snacks sometimes happen in between but never at bedtime as I am usually asleep by 10.

Depends, Robyn! Just make sure that you don't spoil your dinner.

On a day when I'm sticking to a schedule, I eat breakfast between 6:00 and 7:30, then snack at 10:30, lunch around 12:30, snack around 3:30 and dinner sometime between 6 and 8. I eat dessert around 10:00 (I go to bed anywhere between 12 and 3 a.m. ... )
