The Lunar Calendar comes to an end, and the Year of the Rat turns into the Year of the Ox. The Spring Festival Holiday begins with the Chinese New Year celebration, on February 11 and 12. The holiday runs for seven days, with workdays on February 7 (Sunday) and February 20 (Saturday). It coincides with one of the biggest migrations in human history, as people travel home to see families, racking up something like 3 billion trips.
