Do you determine engine rotation by facing the engine from the front or by stading behind it for the purpose of determining firing order?

Engine rotation is determined by sitting in the driver's seat. But engine rotation is of no consequence when determine firing order. It is the rotation of the rotor in the distributor that is important. That is easily found by removing the distributor cap and bumping the engine over and looking at the rotor. Does it rotate clockwise or counter clockwise?
