The lunar calendar is based on the moon's phases (synodic month, about 29.53 days), while the solar calendar is based on Earth's orbit around the sun (tropical year, about 365.24 days). A lunar year is about 354 days, roughly 11 days shorter than a solar year.
To prevent the lunar calendar from drifting away from the seasons, a leap month is added about 7 times in 19 years. Years with a leap month have 13 months.
