it takes like some hours to rotate all that
28 days
it takes 1 month
it takes approximately 29 and one thirds days.
Like Earth's moon, Deimos' axial rotation is synchronous with its orbital revolution as a satellite of Mars. The period of both motions is 30.3 hours.
The moon's gravity doesn't cause those motions, and those motions certainly don't cause the moon's gravity.
The motion of the moon is 2,808 a year

It takes 1 month for the moon to complete each orbit but takes 1 day for it to complete 1 motion
The earth rotates at the rate of 1 rotation each [ 23 hours 56 minutes 4 seconds ].The moon rotates on its axis and revolves around the earth, executing both motions in the sameidentical period of [ 27.32 days ].
29.5 days.
The cycle of the moon's phases runs 29.53 days.
