Can I have my hair cut on New Year's Day?

According to the traditional custom of our country, the people have the custom of burning incense and praying in the temple on the first and fifteenth day of the lunar calendar. This custom comes from Buddhism, which stipulates that Buddhist believers should fast, recite scriptures and respect Buddha on the fifteenth day of the first lunar month, which is actually equivalent to Sunday, and then spread among the people. On the first and fifteenth day of the first lunar month, you shouldn't have a haircut or anything like that. It is unlucky to have a haircut in the first month, and we should also pay tribute to the Bodhisattva.
