Afternoon works for me as well.
What time frame of day is good for other people?
Anytime from 1 to 5 works for me.
Before 1 pm might be a bit early for some of those who need it to be in the afternoon.
After 5 pm might end up being a bit late by the time we are done and people want to head home.
My First Suggestion is around the 2 to 3 PM time frame as a starting point.
That way after chatting and hanging out for a bit we can get a early dinner and people can head out as their schedules need.
