China has used several different calendars because of changes in government structure

How lunisolar calendars work

Despite being called Lunar New Year, the Chinese calendar that the holiday is based on is actually lunisolar, or based on both the sun and the moon. Many religious holidays—including Easter, Ramadan, Chinese New Year, and Passover—do not have fixed dates according to the now-ubiquitous Gregorian calendar.

The Lunar New Year was widely celebrated until Mao Zedong and the Communist Party

In the 1960s, Mao ushered in the Cultural Revolution, an attempt to make China a more modern, industrialized nation. In keeping with this, he banned traditional holiday customs in favor of “revolutionary” actions like chanting Communist Party slogans and engaging in a “self-criticism” ceremony. These changes weren’t very popular and were quickly reversed after Mao’s death.

The custom is supposed to increase participants’ good karma, bringing them extra blessings for the year to come.

January is named after Janus, the Roman god of transitions

In 46 BCE, Julius Caesar introduced the Julian calendar, which established Jan. 1 as the beginning of the new year. The month was named after Janus, the Roman god of transitions, who had two faces—one looking back at the past, the other forward to the future. While the Babylonians also made promises as part of their celebration of the new year, the Roman tradition became more focused on looking backwards to plan for the coming year.
