mmm just to add to that side of rotation of the turbine engine is a tricky one! sometime your fan N1 shaft turns one way and the N2 turns the other way to cancel out the centrifugal force. if not you will be internally pushing those rudders beyond the limit or might have to take a brick in ur travel bag!

so I guess the engine turns both ways! but the fan module or the N1 is what you see turning from outside! and the turning side depend on the manufacturer. And as someone said earlier the white snake on the tip of the fan module will tell u which way it turns.

Normally direction of the rotation is judged from the back of the engine facing the front of the airplane.

there are some contra-rotating and counter rotating configurations in turboprops and turboshafts. let me stop there!
