The Jewish and Chinese calendars are solar-lunar. A month is defined as the time it takes for the moon to circle the earth. A year is defined as the time it takes for the earth to circle the sun. Since the lunar months don't quite add up to a year, an extra month is added in leap years. In both calendars, leap years occur seven times every 19 years. Chinese and Jewish leap years don't always coincide. Even though both calendars add a month 7 times every 19 years, the leap years don't have to take place the same year. Jewish and Chinese holidays often occur on the full moon.
