I pertsonally think many times the best time to hunt a stand is as soon as you hang it, before giving anything time to know its there!
BUT this can depend on how stealthy you were in setting stand up
if you drove a big atv/utv, had a bunch of folks helping and sweating and making a LOT of noise
well then, YOU can still use it first time out
but some times it comes down to your feelings
a deer can walk by any time, and NO one knows why or how they will react to disturbances
or human scent

as this many times comes down to WHERE the disturbance is at, how deer are in YOUR area, some tolerate more human activity and pay little to no attention to it, and in some places, deer will LEAVE a area for a while if they find human scent in it

so, sadly, there is NOT correct answer or really wrong one IMO

if you want to hunt it, HUNT it,
if you THINK< deer will be bothered by all the ruckus you made setting stand up
\ wait a few days
or WAIT for the better wind for that stand!
as wind does matter again, more so in some pl;aces, but all deer live by there noses IMO!
