suppose there are three days in one month. the day is 24 hour and night also 24 hour. the first day of above mentioned month starts now, when the sun starts to set suddenly the rotation of sun and earth changes such that the new days starts rather than starts of night. Now question is how many days then are in one month?

Explanation:
Yes! All the planets in our solar system spin on their axes (so does our Sun!) and so they have day and night cycles. There are differences, however, in the length of day and night — the cycles are made even more complex by the tilt of a planet's axis and its rate of orbit. Some planets rotate faster than Earth and some rotate slower. Mars has a day and night cycle similar to Earth. Mars rotates on its axis once every 24.6 hours. Venus turns once on its axis every 243 Earth days (which is only slightly longer than it takes for Venus to go around the Sun!). Mercury's day and night cycle is more complex. Mercury rotates one-and-a-half times during each orbit around the Sun. Because of this, Mercury's day — from sunrise to sunrise — is 176 Earth days long. The larger planets spin much faster. Jupiter rotates once every 10 hours, Saturn spins once every 11 hours, and Neptune completes a rotation in 16 hours. Pluto, at the farthest reaches of our solar system, spins on its axis once every 6.4 days.
Something to ponder: Does Pluto even have a “day” and “night” like we think of on Earth? Pluto is so distant from the center of our solar system that our Sun would look like a very bright star in its sky!
