You can see the moon for about 8 hours in the day
It really depends on what phase the moon is in.
Two hours on the moon would be the same length as two hours on Earth, as time is consistent regardless of location. The moon's day is about 29.5 Earth days long, so two hours on the moon would only represent a fraction of its day-night cycle.
Viewed from any single place on earth, the moon is 'up' and in the sky for about 12-1/2 hours of every day.
A day on Jupiter's moon Io lasts about 42.5 hours, and it experiences constant daylight due to its proximity to Jupiter, which causes the moon to be tidally locked. As a result, Io does not have distinct day and night cycles like we have on Earth.
When the moon is visible during the day, it is called a "day moon." This occurrence happens because of the moon's position in its orbit around Earth where it can be seen from Earth in daylight hours.
If you mean "how many hours are IN one day", then there are 24 hours in a day.
About 655 hours.

A lunar day is 27 days, 7 hours and 43.2 minutes long. This is the time it takes the moon to complete one full rotation with respect to the sun.
