Day on calendar vs when you have intercourse

C&G <3 • Whelp we are a comfy family of 4
So my husband works 2nd shift and I'm working a middle of the day shift PT (11 am to 5pm). That being said we are night owls. He gets off 11 or 12 at night and we usually have fun around an hour after that(aka 12 or 1am). So when I log I'm wondering should i log at 1am when it has rolled to the next day or the day "before". Or does it even matter?
