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 beteen the to floods as about 365 days， that is， one year。
At the same time， the ancient Egyptians also found that hen the rising tide of the Nile came near today's Cairo City， it as precisely hen 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 Ne Year's Day。
Ne Year's Day in China， aording to legend， originated from one of the three emperors and five emperors， ith a history of more than 3000 years。
The ord “Ne 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 Ne Year's Day in Zhengshuo"。
