Most of the world uses the Gregorian, or Western, calendar, which is based on the time it takes for the Earth to revolve around the sun. In this system, every year has 12 months, each lasting 30 or 31 days with the exception of February. Because it takes 365 days, 5 hours, 48 minutes and 46 seconds for the Earth to revolve around the sun, every fourth year – or leap year – has an extra day. The Chinese use a lunar calendar based on the cycle between new moons, which takes 29.53 days, on average. Each of the 12 months in a lunar calendar lasts one lunar cycle.
