There are many different answers because the attack lasted different lengths of time at different locations. The 'Pearl Harbor' attack actually encompassed Pearl Harbor, Ford Island, Hickam Field, Schofield Barracks, and more. The attack was divided into three waves, each arriving at a slightly different time and departing separately.

Japanese commanders considered extending the attack but could not get the planes ready for launch until late afternoon, meaning they would be recovered after dark; they were not trained for this. An alternative was to maintain position and attack again on the 8th but the senior officers knew that to do so invited submarine attack and also that their ships did not have enough fuel to return home if they maneuvered another day. and that is one of the most crappy was to spend your morning.
