What is the difference between time period on moon and time period on the earth???

Since ancient times, lunar calendars have been based on thirteen months of 28 days each, reflecting the lunar cycle. ... In fact, it takes the Moon the equivalent of 27.3 Earth days to complete a single rotation on its axis, the same amount of time it takes to complete a single orbit around Earth.
