it never stops spining.
One complete rotation of the earth on its axis is called ONE DAY
It takes 1 sidereal day for the to earth to spin on its axis. That is 23.93447 hours.

27.32 earth days
No. Each of those "days" of which the question speaks is the length of time it takes for the earth to spin on its axis. The question is actually referring to the moon, which takes 27.32 days to spin once on its axis.
For one axial rotation it takes 243 Earth days.
10 hours. Or two and a fraction per Earth day.
They spin at a different rate on their axis than the Earth does on its axis.
A Mercurian "day" the (time it takes it go spin once on it's axis) is equal to 58.65 earth days. Mercury turns on it's axis very, very slowly.
Venus rotates once in 243 days.
365 days in a year 366 days in a leap year.
The moon takes about 27.3 days to spin around its axis once, which is the same amount of time it takes to complete one orbit around Earth. This synchronous rotation is why we always see the same face of the moon from Earth.
