In ancient times, there was a young man named Wan Nian.
古时候，有个名叫万年的青年。
When he saw that the festivals were very disorderly at that time, he had the intention of setting the festivals.
万年看到当时节令很乱，就有了想把节令定准的打算。
But there has been no way to calculate the time.
但他一直找不到计算时间的方法。
One day, he was tired of cutting firewood and sat in the shade of a tree to rest.
一天，他上山砍柴累了，坐在树阴下休息。
The movement of the shadows inspired him. He designed a sundial to measure the time of the day.
树影的移动启发了他。他设计了一个测日影计天时的晷仪，测定一天的时间。
Later, the dripping spring on the cliff inspired him, and he started to make a five-layer leak pot to calculate the time.
后来，山崖上的滴泉启发了他的灵感，他又动手做了一个五层漏壶，来计算时间。
Day after day, he found that every 360 days, the four seasons are repeated, the length of the day is repeated.
天长日久，他发现每隔三百六十多天，四季就轮回一次，天时的长短就重复一遍。
At that time, the emperor was Zu Yi, and he was often distressed by the unexpected weather.
当时的国君叫祖乙，也常为天气风云的不测感到苦恼。
Wan Nian took the sundial and the leaky pot to the monarch and explained the principle of the sun and the moon running.
万年知道后，带着日晷和漏壶去国君，对祖乙讲清了日月运行的道理。
Zu Yi felt justified when he heard it.
祖乙听后大悦，感到有道理。
So he built the Sun and Moon Pavilion in front of the Temple of Heaven, and built the sundial platform and the leaky pot pavilion.
于是他在天坛前修建日月阁，筑起日晷台和漏壶亭。
Zuyi hopes to measure the law of the sun and the moon, to calculate the exact time of morning and evening,
祖乙希望能测准日月规律，推算出准确的晨夕时间。
And to create a calendar for the benefit of the people.
创建历法，为天下的黎民百姓造福。
After the establishment of the calendar, Wan Nian offered a proposal.
历法创建完毕后，万年提出一件事。
"Now it's the end of twelve months, the old age is over. Please set a festival for the king."
“现在正是十二个月满，旧岁已完，请国君定个节吧”。
Zu Yi said, "Spring is the first year of life, so it's called Spring Festival."
祖乙说：“春为岁首，就叫春节吧”。
It is said that this is the origin of the Spring Festival.
据说这就是春节的来历。

春节习俗
1、年夜饭
年夜饭，又称年晚饭、团年饭、团圆饭等，特指岁末除夕的阖家聚餐。年夜饭源于古代的年终祭祀仪，拜祭神灵与祖先后团圆聚餐。年夜饭是年前的重头戏，不但丰富多彩，而且很讲究意头。吃团年饭前先拜神祭祖，待拜祭仪式完毕后才开饭。
2、压岁钱
压岁钱，年俗之一，年晚饭后长辈要将事先准备好的压岁钱派发给晚辈，据说压岁钱可以压住邪祟，晚辈得到压岁钱就可以平平安安度过一岁。压岁钱在民俗文化中寓意辟邪驱鬼，保佑平安。
