I work nights. How does this work when counting calories???

I eat a meal around 12 -1 am so if I am on a 1300 a day calorie meal plan which day should I count these calories towards? Day A (before 12am) or Day B (after 12am)?I work nights. How does this work when counting calories???
From the time you wake up until the time you go to sleep should be considered 'one day' regardless of what time the clock reads.I work nights. How does this work when counting calories???
Calories are 1/2 at night, because of the gravitational pull of the moon (compared to the gravitational pull of the much larger sun during the day).





Also, chocolate at Christmas has 0 calories - IF you are a believer.
