You'll be fine...dark cycle will be from 6 PM to 6 AM? If so, give them the extra hours of dark instead of light when you make the shift.
So if lights off at 5 AM on a Wednesday, they won't come back on until 6 AM Thursday...a 25 dark period.

But quite honestly, it probably would not make a bit of difference one bit. Just make the switch when you're ready and it will be fine.

A lot of people start with a 36 hr dark period so I can't imagine when you start will matter. I like to keep it as natural as poss and cut the hours at the end of its day.
