The Nepalese calendar, also known as the Bikram Sambat calendar, is 67 years and 8.5 months ahead of the Gregorian calendar that is commonly used in most parts of the world.
The Bikram Sambat calendar was introduced by King Bikramaditya in the 57th century of the Hindu calendar, which roughly corresponds to the year 1000 AD in the Gregorian calendar. The calendar is based on lunar cycles, with each year consisting of 12 lunar months. The months are named after different astronomical bodies, and the calendar is used to determine the dates of many festivals, holidays, and other important events in Nepal.
The reason for the 67-year difference between the Nepalese and Gregorian calendars is not entirely clear, but it is believed to be due to a difference in the way that leap years are calculated. In the Gregorian calendar, a leap year occurs every four years, while in the Bikram Sambat calendar, leap years occur in a more complex pattern that takes into account the position of the sun and the moon.
Despite the difference in calendars, the Gregorian calendar is also widely used in Nepal, especially for official and business purposes. However, the Bikram Sambat calendar remains an important part of Nepalese culture and tradition, and is celebrated with great enthusiasm during the Nepalese New Year, which falls in mid-April.
