A lunar month, which is the time it takes for the Moon to complete one full cycle of phases, is approximately 29.5 days long. This period is known as a synodic month, starting from one new moon to the next. Due to this average length, lunar months can vary between 29 and 30 days.
A lunar calendar year typically has about 354 days. Over 19 lunar years, this totals approximately 6,726 days (19 x 354). If an extra month is added 7 times, that adds about 30 days (as a lunar month averages around 30 days), resulting in a total of approximately 6,756 days. Thus, there are about 6,756 days in 19 lunar calendar years with the extra month included.
