That depends on what you call a "lunar cycle". -- If you mean the time it takes for the moon to return to the same place on the map of the stars, that's 27.32 days and exactly one (1.000) axial rotation of the moon. -- If you mean the time it takes for the moon to display a complete cycle of phases in the sky, that's 29.531 days, or 1.081 rotations.
The complete cycle of phases ... the moon's appearance ... repeats every 29.53 days.
365 days
Sort of. The definition of a month is one moonth ... one lunar cycle.
27 1/2 days to occur and 29 1/2 days to see. is this true? and how does that work? No, that's not quite it. You see the phases as they occur, and that process takes 29+ days. It is the sidereal period of the moon, the true 360 degree orbit around earth, that takes 27+ days. This is very counter-intuitive and you need to understand the difference between synodic and sidereal cycles to understand the difference. Once you understand this difference it will be very clear.
The moon goes through a complete cycle of its phases in 29.53 days.
About 29 days.
29.53 days

It takes about 30 days on average
A full lunar cycle is 29 1/2 days, on average.
The average is 28 days but it varies with each girl.
The complete cycle of phases ... the moon's appearance ... repeats every 29.53 days.
Also seven days. Possibly because the lunar cycle divides by 4. There is a good study in wikipedia.org which lists many cultures approach.
365 days
