Explanation:

[STC001953] China will begin celebrating the beginning of their new year today, and the festivities will continue for the following 15 days. Chinese New Year operates around a lunar calendar, meaning it’s based on the phases and movements of the moon; thus, the exact date changes every year. On the calendar that Westerners are most accustomed to using, the holiday often takes place between the 21st of January and the 20th of February. Because it is the most extravagant holiday in China, the people of that country go to great lengths to celebrate. Even though it is only a seven-day official holiday, many people continue to celebrate for much longer than that.
