If the earth stopped rotating, days would be about 365x longer.

I wanted to figure out a more exact answer, but I'm hung up on the fact that the length of a day is influenced by rotation and revolution together.

I have a feeling this requires calculus. If Sir Isaac Newton were here, I think he'd know what to do.

It could be tidally locked to the sun too. Then days would truly cease to exist, you'd just have a hot side and a cold side.

It could, and eventually would, but the premise of this comic is "the earth has stopped rotating", not "the earth is now rotating at 1 revolution per year".

Tidal locking still requires the planet to be rotating

365x24=8760

Open 8760 hours a day, 7 days a week

you've got it. the period of the sun up/sun down cycle would be the orbital period.

365.25 days I believe is the better approximation because it's the rough time it takes Earth to be in the same spot - hence the leap years
