Spring Festival
=============
Spring Festival is the most important of the traditional Chinese holidays. It is 15 days starting on from the first day of the first lunar month of the Chinese calendar. The Chinese New Year period ends with Yuan Xiao Jie, on the fifteenth day of the festival.

It is possible that the beginning of the year began with month 1 during the Xia Dynasty, month 12 during the Shang Dynasty, and month 11 during the Zhou Dynasty in China, but intercalary months were added after month 12 during both the Shang Dynasty according to surviving oracle bones and the Zhou Dynasty according to Sima Qian. The first Emperor of China Qin Shi Huang changed the beginning of the year to month 10 in 221 BC. Whether the Spring Festival was celebrated at the beginning of these months or at the beginning of month 1 or both is unknown. In 104 BC, Emperor Wu established month 1 as the beginning of the year where it remains.
