Reason for taking BC at same time

Hey, guys
Not that this applies to me, but I was just wondering, what is the reason behind the directions to take the pill at the same time (within 2 hours) every day? How does changing times affect the pills effectiveness?

Just curious.

Each pill only lasts in the system for a certain length of time before it starts to decline in strength.

The half-life (the time it takes for half of the hormones to leave your bloodstream) of most progestins is around 26 hours, the half-life of estrogen is about 28 hours.
