Why do default to measuring calories per day and not hour or week?

Question

Are you not constantly in a surplus after every meal and deficit prior to meals?

Answer 1

Because what matters is the surplus/deficit over a longer time span.

If you look at it hourly you would constantly go from “yeah I’m in a deficit” to “fuck, I am in a massive surplus”.
Most peoples meal cycle is one day, and they eat roughly the same amount each day. So we can extrapolate from one day to a week or a month.

If you were doing something like fasting 3 days and then eating for 4 days, you would need to count the overall calories for that 7 day period to get an accurate picture.
