Origin of the New Year calendar

In the language and life newspaper, author Quang Nguyen wrote the New Year’s Day with the Western and Ta calendars. The Western calendar and the Ta calendar are familiar names. Same role as a unit of time but the Western calendar and the Ta calendar have different calculations, the same year but the New Year of the Calendar Year always comes earlier than the New Year of the lunar year. This calculation is mainly based on the origin of each calendar, but not everyone understands the origin and origin of each calendar.

The Gregorian calendar, called the Western calendar, takes the time of one earth’s rotation around the sun to make a year. That rotation takes exactly 365 days and nights plus 5 hours 49 minutes and 40 seconds. The Gregorian calendar, which used the legend of Jesus’ birth year, serves as the first year to calculate the years in the world. The solar calendar was used in the 4th century (AD), initially popular in Western countries of Christianity. After gradually gaining recognition and popularity around the world, it is called the Calendar and the era is recorded according to the Gregorian calendar called BC. According to the Gregorian calendar, there are 5 months of missing months as months: 2; 4; 6; 9; 11 months of 30 days each month, only 28 days of February and 7 months of full month are: 1; 3; 5; 7; 8; ten; 12 months of 31 days each.

As for the origin of the lunar calendar today, it comes from the Chinese calendar, in China thousands of years BC has formed many different types of calendars. From the Warring States period to the Western Han period, about 2000 BC until the early years of the common era BC often used the following three types of calendars: Lower Calendar, Zhou Calendar and Qin Calendar. All three types of calendars take 365, 25 days to measure time a year. Lunar calendar to distinguish it from the Western calendar, can be roughly called the Ta calendar or another name is called Calendar because it is suitable for calculating crops in agricultural production. The lunar calendar takes the average time of a month according to the moon’s rounding cycle, while the one-year period is based on the period of the earth’s rotation around the sun. A rotation of the moon around the earth is a period between two full moons or between two moons. That cycle, if counted correctly, is 29 days and nights plus 12 hours 44 minutes and 03 seconds, so that it is counted as 30 days for the full month and 29 days for the missing month. Chinese New Year is the first day of a year, Chinese people call by many different names such as Nguyen Chinh, Nguyen Xuan, Nguyen Dan, Nguyen Nhat and Nguyen Soc … The most common name is Nguyen Dan first appeared. in the verse of Tieu Tu Van in the Southern period of the Luong Dynasty:

“New Chinese New Year air.
Kim long life record million.

Vietnamese do not know when they usually call the opening day of a lunar year, not even a day, but two or three days of the first day of the New Year. This way of calling is derived from the reading of the pronunciation of Sino-Vietnamese character, but to talk about certain holiday such as Doan Ngo, Mid-Autumn Festival, Tet and Tiet have the same meaning, and if it is said New Year, it means the holidays to celebrate the old year and to welcome the new year according to the traditional customs of the Vietnamese people.

Tet in Vietnam has very unique and distinctive nuances, it can be said that observing and researching names in language can discover many interesting things. Language is not only a mirror that reflects the objective reality of a nation and a nation, but language research also helps us to partly understand the habits and customs of our ancestors. .
