Sleep Conflicts

My work schedule is kinda crazy. I work 2 days on 2 days off 3 days on 2 days off (repeat). The hours rotate between 7 AM to 7PM then 7PM to 7AM. So here is my question.

Nights like tonight I am working overnight till 7am. The new day starts at 12am on my calorie counter even though I'll be up till 7am and then sleep from 8am till 1pm.

For those who understand metabolism effects with the sleep cycles....

Should I be counting my calories on a normal schedule and just allow for the overlap, or should I retro-update my overnight calories making sleep the definitive line between updates? I realize it is all a bit confusing but I'm just curious.
