How do Asians take into account the 5 missing days in the lunar calendar they use?
First of all, it’s not Asians in general but the CHINESE specifically. The Chinese Lunar New Year is the longest chronological record in history, dating from 2600 B.C. when the Emperor introduced the first cycle of the zodiac. Like the Western calendar, the Chinese lunar calendar is a yearly one. However, this calendar is based on the movements of the moon, with each month beginning a new moon. Because of this cyclical dating, the beginning of the year can fall anywhere between late January and the middle of February. A complete cycle takes 60 years and is made up of five cycles of 12 years each.
