The Moon completes an orbital revolution around the earth in 27.32 days,
and it displays a complete cycle of 'phases' in about 29.53 days, which is approximately a month. (More precisely 29.53059 days.)
27.5 days is given as the (sidereal) orbital period of the moon, but this is slightly different from the moon's synodic period. A full lunar cycle takes one synodic period to complete.
29.531 days is the synodic cycle of the moon, what we call the lunar cycle. This is the length of time it takes for exactly one entire cycle of lunar phases to occur. A synodic orbit or period is the length of time it takes for a body to orbit a planet bringing the body into the same alignment with the sun, relative to the planet. New moons, for example, are separated by 29.531 days, the synodic period. Because the earth is moving in its anti-clockwise orbit, the moon has to orbit a little more than 360 degrees in order to align with the sun again.
-- After the moon passes any particular star in the sky,
it'll take 27.32 days to pass the same star again.
-- After the moon passes the sun in the sky (a New Moon), it'll take
29.53 days to pass the sun again (next New Moon).
The cycle of lunar 'phases' is about 29.53 days.
It starts with an egg, then it hatches into a caterpillar. Then it becomes a pupa. Then it slowly transforms into a moth.
The lunar cycle is 1 hour at the most. It can sometimes only last for a few seconds.
The cycle of phases repeats with a period of 29.53 days. (rounded)

A Lunar month is 29 1/2 days.

The answer is 28 days, so a question asked is why we didn't have our months made by the lunar cycle.
They last forever.
1 lunar cyle equivelent to 29.53059 so what happens in a complete lunar cycle is the lunar cycle forms into a 360 circle

The lunar cycle of phases is about 29.5 days. As the moon rotates and revolves around the earth, and the earth rotates and revolves around the sun, the shadows cast by the shifting positions of the moon and earth cause the moon to wane, wax, and "disappear". This is known as the lunar cycle.
The answer is 28 days, so a question asked is why we didn't have our months made by the lunar cycle.

the lunar cycle takes about four weeks
The lunar cycle is caused by the revolution of the Moon about the Earth.
There is no "last" in repeating cycles. Whatever phase you are thinking of, the next one restarts the series.
The Chinese calendar repeats after 12 years.
The time it takes for the moon to travel around the earth one time is called a lunar cycle. A lunar cycle generally takes about 29 days to complete, but it can be shorter or longer. A lunar cycle begins with a new moon.
