What is the lunar calendar used for?

Some cultures use lunar calendars, which are based on the timing of the moon's orbit of the Earth, rather than solar calendars, which are based on the Earth's orbit of the sun. One lunar calendar in use today is the Islamic calendar, the Hijra. Some calendars, like the Hebrew calendar, are luni-solar, a cross between the lunar calendar and the solar calendar. They have months that begin at the time of the new moon, but they also have leap months added every few years to keep pace with the solar cycle. Regarding what they're used for, the primary purpose today is to know the time of traditional, especially religious, feasts and other observances. Lunar calendars in everyday use today is rare since the invention of electric lighting, yet might still be handy to some hunters, fishermen, or lunologists.

Why would a lunar calendar be inaccurate?

In all lunar calendars the first day of each month depends on the phases of the moon. Some calendars begin their month at the start of the new or dark moon while others do not start the month until the first new crescent moon is observed. The actual time it takes for the moon to go through a complete phase cannot be perfectly subdivided by any full number of days. It takes a little more than 29.5 days for this phase to occur, and, thus, over time, lunar calendars will begin to slip and become more and more inaccurate over time. Increasingly complex fractions and dividing schemes have been created to make lunar calendars more accurate.

What determines the length of a year and how is it calculated in different calendars?

The length of a year is determined by the time it takes for the Earth to orbit the sun. In different calendars, the length of a year is calculated based on different methods of tracking this orbital period. For example, the Gregorian calendar used in most of the world today calculates a year as 365 days, with an extra day added every four years in a leap year. Other calendars, such as the Islamic calendar, are based on lunar cycles and have shorter years.
