# How many Lunar months are there in one year?

There are 12.36 lunar months in one Greogorian year [nearly same
for solar year], since lunar month consists of 29.53 days. However
there are only 13 lunar months if at all it is a lunar year.

12 lunar months are a bit shorther than a "solar year" - about 11
days shorter. In the case of the Islamic calendar, what they call
year is by definition exactly 12 lunar months - but this year is
shorter than a year of the Gregorian calendar, by about 11
days.

### How many months are in a lunar calendar?

One year of a lunar calendar has 12 months, but it's about 11
days shorter than one year of the Gregorian calendar.
A lunisolar calendar has months that are based on the cycle of
the moon phases, but it also has leap years to keep the average
length of a year close to the time it takes for the earth to orbit
the sun. A regular year of a lunisolar calendar has 12 months, and
a leap year has 13 months.

### Why are lunar months a problem for lunar calendars?

A lunar calendar is based on lunar months (the cycle of the
moon's phases takes 28 days). Since this cycle is fairly constant,
the months all have the same length. The problem arises because no
whole number of lunar months corresponds to one year; the closest
is 13 months, equal to 364 days. This leaves an overhang of one and
a quarter days each year which must be accounted for in a similar
manner to leap years.
