Neptunes days are 16 hours, 6 minutes and 36 seconds in averate.Being a gas giant Neptune isn't solid so the closer one gets to the poles the faster the spin about 12 hrs or slower at it's equator about 18 hrs with eddies and whirlpools in between. try watching a river at its bend and drop a bit of wood as a reference----not all of the water moves at the same speed
