New year's Eve

The night of the last day of the lunar month and the last day of the lunar year (the 30th day of the month and the 29th day of the month) are called "New Year's Eve". It is connected with the Spring Festival (the first day of the first month), which is a day for people to say goodbye to the old and welcome the new. Since the big month in the lunar calendar has 30 days and the small month has only 29 days, New Year's Eve's dates are different from those on the 29th and 30th.
