“再坚持一下，2262年有两个春节”
引发热议。
根据万年历查询，2262年1月21日是农历正月初一（第一个春节），2月20日是闰正月初一（第二个春节），这种闰正月现象十分罕见。
The unusual prospect of two Spring Festivals occurring in a single year — in 2262 — has sparked widespread discussion online.
According to the calendar, the year 2262 will see two Chinese New Year's days: the first on January 21 (the first day of the first lunar month) and the second on February 20 (the first day of the intercalary first lunar month). Such an occurrence of an intercalary first month is exceptionally rare.
intercalary /ɪnˈtɜːrkəˌleri/ adj.（历法）闰的
2262年将会有两个春节，到时候会不会放两次假？是不是可以收两次压岁钱？
先说说为何会有两个春节——这都是月亮“惹的祸”。中国农历历法是根据月相的圆缺变化，来计算一个月的天数的，在天文学上被称为“朔望月周期”。
“朔”所在日为初一，是人们完全看不到月亮的时刻；“望”所在日为十五，就是满月的时刻。
The reason behind the dual Spring Festivals lies in the moon's movement. The traditional Chinese lunar calendar calculates the length of a month based on the phases of the moon, known astronomically as the synodic month. The first day of a lunar month, known as shuo, marks the moment when the moon is not visible from Earth, while the 15th day, wang, is the full moon.
synodic /səˈnɑːdɪk/ adj.（天体）会合的
但如果一年当中只有12个农历月，那么年长平均是354天，这要比阳历的年长少了大约11天，长此以往，就会出现寒暑颠倒的现象，春节有可能在夏天来过。
因此，古人想到了“置闰”的方法。通过每两到三年增加一个闰年的办法，使得农历的平均年长与阳历的年长相一致，而多出来的这一个农历月就是闰月。
结合“置闰”规则，2262年闰正月，所以，2262年有两个春节。
If a year contained only 12 lunar months, the average lunar year would be about 354 days — roughly 11 days shorter than the solar year. Over time, this would lead to seasonal misalignment, with Spring Festival potentially falling in summer.
To address this, ancient Chinese astronomers introduced the "intercalation" system, adding an extra lunar month every two to three years to synchronize the average lunar year with the solar year. This additional month is the intercalary month.
Under these rules, 2262 will have an intercalary first month, hence two Spring Festivals.
由于月球、地球、太阳，三者之间的相对运动并非一成不变，因此“朔望月周期”有长有短。农历一年中就出现了大月30天、小月29天的分法。
为了保证农历每月的初一必须是朔月，所以大小月的安排也不是固定的，这需要通过观测和科学推算加以确定。
这种情况，大约三到五年就会出现，有时甚至连着几年都会出现没有大年三十的春节。2025至2029年，就连续5年没有大年三十。
Because the relative motions of the moon, earth, and sun are not constant, the length of a synodic month varies. Thus, the lunar calendar features longer months of 30 days and shorter ones of 29 days. To ensure the first day of each lunar month aligns with the new moon, the arrangement of long and short months is not fixed but determined through observation and scientific calculation.
Such variations occur approximately every three to five years. Sometimes, several consecutive years may even see Spring Festivals without a "Chinese New Year's Eve", as will be the case from 2025 to 2029.
据了解，早在2007年《全国年节及纪念日放假办法》公布不久，国家发改委和假日改革课题组人士就对这种特殊情况作出了明确解释，闰年时，如果出现两个端午节和两个中秋节的情况，只有一个端午或者中秋节放假，
原则上第一个月的节日为假日
。
On Wednesday, the hashtag “2262 Two Spring Festivals But One Holiday” once again topped the trending charts.
According to explanations provided by the National Development and Reform Commission and the Holiday Reform Research Group, in intercalary years with two occurrences of the same festival (e.g., two Dragon Boat Festivals or Mid-Autumn Festivals), only the first instance is designated as a public holiday.
如2009年农历就有五月和闰五月，端午对应的日子分别是阳历的5月28日和6月27日，但最终端午节假期被安排在5月28日。
每年放假如何安排，都会在前一年年底由相关机构公布，一般而言，放假的日期安排、长短，不会对社会生活造成影响
。
Annual holiday arrangements are typically announced by relevant authorities toward the end of the preceding year. Generally, the scheduling and duration of holidays are planned to minimize disruption to social life.
