Lunar Calendar
A lunar calendar is a system that tracks time based on the phases of the Moon. It typically consists of months that correspond to the Moon's cycles, which take about 29.5 days to complete. As a result, lunar months can be either 29 or 30 days long. Unlike the solar calendar, which aligns with the Earth's orbit around the Sun, a lunar calendar year is shorter, about 354 days, leading to its months shifting over seasons. Cultures using lunar calendars include many in Asia and the Islamic world, often for religious and agricultural purposes.

A lunar calendar is a system of measuring time based on the phases of the Moon. Unlike the solar calendar, which is based on the Earth's orbit around the Sun, a lunar calendar typically consists of 12 months, each beginning with the new moon. This results in a year of about 354 days, which is shorter than the solar year of 365 days. To keep the calendar aligned with the seasons, some lunar calendars, like the Islamic calendar, do not add extra months, while others, like the Hebrew calendar, occasionally insert a leap month.
