元旦的由来英语

Around 50，000 B。C。 the ancient Egyptians settled on both sides of the Nile River。 From long-term observation， they found that the Nile River flooded regularly。 

They recorded the time on bamboo poles every time。 From this， they learned that the time between the two floods was about 365 days， that is， one year。

At the same time， the ancient Egyptians also found that when the rising tide of the Nile came near today's Cairo City， it was precisely when the sun and Sirius rose simultaneously from the horizon。 

So the ancient Egyptians set this day as the beginning of the year。 This is the earliest origin of New Year's Day。

New Year's Day in China， according to legend， originated from one of the three emperors and five emperors， with a history of more than 3000 years。 

The word “New Year's Day” first appeared in Jin Shu: "Emperor Zhui takes the first month of Mengxia as the yuan， but in fact it is the spring of New Year's Day in Zhengshuo"。
