What day of the month does the New Year begin on each year's lunar calendar? Please say the significance of New Year.

The Spring Festival, referring to the festival that begins on the first day of the first month of the lunar calendar, is a festival traditionally celebrating the new year in many parts of East Asia. The traditional name for the Spring Festival is New Year, but it is often referred to verbally as the New Year; in ancient times, the Spring Festival used to refer exclusively to the beginning of the spring season, and the Lunar New Year was known as "New Year's Day", meaning the first day of the year. It is difficult to trace the origin of the Chinese New Year custom, but it is generally believed that it originated in the Yin and Shang dynasties in China, when sacrifices were made to the gods and ancestors at the end of the year (the Lunar New Year Festival); it is said that the Chinese New Year was first celebrated during the time of Yao and Shun. The first month of the lunar calendar marks the beginning of the year, and the first or middle part of the first month, in most cases, coincides with the beginning of spring. The timing of the festival is believed to be related to the effects of agricultural labor; the last day of the year on the lunar calendar (the 30th day of the big month and the 29th day of the small month) is called "New Year's Eve", and on the evening of New Year's Eve, the whole family is reunited for the New Year's Eve dinner (the last meal of the year on the lunar calendar), after which there is a custom of handing out New Year's Eve money and staying up all year long to observe the New Year's Eve, which is said to be observed from the last day of the previous year on the lunar calendar to the first day of the next year. The customs of the Spring Festival are many and varied. Customs vary from time to time, from region to region, and from ethnic group to ethnic group.
