What Day Is It?

I've noticed when I've been reading particularly British scripts that they don't seem to put what day it is, such as Day 1/Night 2 etc which is surely important for clothing changes. The Frasier and Friends scripts are the only ones that seem to do it and most scripts are over several days.

Edit: Father Ted does it too.

How odd. Father Ted is probably the one where they're most likely to be wearing the same thing the next day.

Perhaps British producers are capable of working out for themselves when the script goes over to another day.

I usually state in my scripts when it's the next day.
