It's 10:41 when Dustin and Max start searching for Eddie in the family video Robin and Steve work at.
It's either ~5:15pm or ~2:25am when the gates open.
Considering it's march it's likely the second. Because it would be pretty dark for 5:15pm.
(also considering that Lucas, Max and Erica go into the creel house during sunset)
So I wanted to look something up for a reblog and watched the scene where Max explains to Dustin what happened with Chrissy and Eddie and the lights and I saw this:
See the clock to the right? It's not in focus and Netflix doesn't want to give me HD Screenshot material but you can see that it's almost 10 o'clock.
So canonically Vecna killed Chrissy less than 9 hours before Mike's plane was departing. (Potentially the next bigger city with an airport is 30-60 minutes away because I doubt Hawkins has an airport, so it would more like 8 or 7 hours before Mike had to leave his house).
He wasn't using Mike as tool or waited for him to be gone. He killed Chrissy in close proximity to someone who knows about the UD and the flickering lights less than 9 hours before Mike was gone.
There is no way Henry would jeopardize his plan like this
