Spring is one of the four seasons. After winter, before summer.


Calendar period

In the Northern Hemisphere (half a year off in the Southern Hemisphere): April, May, and June are classified by quarter in the Japanese fiscal year. In English, these three months are called spring quarter. March / April / May in meteorology. Astronomically, from spring to summer solstice. "Spring equinox" and "summer solstice" here are not "Vernal Equinox Day" and "Summer Solstice Day", but the moment when the solar ecliptic becomes 0 ° or 90 °. From the beginning of spring to the day before the beginning of summer January / February / March according to the lunar calendar. Close to the top, but off by up to half a month. The JR Group's special train operation is divided into four months from March to June. In the West (especially the United States, Germany, etc.), it may be from the vernal equinox day to the summer solstice day.

Climate period

It is said to be "summer all year round" near the equator and "winter all year round" in the polar regions, and it is sometimes said that there is no spring. In the Arctic and Antarctica, snowmelt and thaw may be the beginning of spring.


Early spring (Mengchun) From January of the lunar calendar or from the beginning of spring to the day before Jingzhe. Nakaharu (Nakayo) From February of the lunar calendar or from Jingzhe to the day before Qingming. Late spring (seasonal spring) From March of the lunar calendar or from Qingming to the day before the beginning of summer.


Spring is a time when the temperature starts to rise from the cold winter, and although it is still chilly in the morning and evening, it gets warmer during the day. Along with autumn, it is said to be the mildest season of the year with the best climate. It is the time when snow and ice melt and plants sprout. The cold gradually eases, the plants sprout, the flowers bud, and they are in full bloom. As the days get longer, insects in the ground begin to move. The cherry blossoms are falling, the greenery of the trees is gradually increasing, the number of hot days is increasing, and the end is reached. In Japan, March is changed every year, and there are various breaks (although it varies slightly depending on the year, reorganization, laws and systems are implemented, ordinance-designated cities, core cities, etc. are merged, etc. Is often done, and this time is a big milestone). It is also the season of encounters and farewells, such as graduation ceremonies, entrance / entrance ceremonies, and personnel changes. Cherry-blossom viewing is treated on top of this. See the season for what you can get in spring. By relieving the cold of winter, the activity of living things generally becomes active in spring. In addition, meltwater in heavy snowfall areas is a valuable water resource and is closely related to rice planting in Japan. On the other hand, it may cause avalanches and snowmelt floods in some areas. In addition, a developed cyclone passes through the Pacific Ocean side and the temperature is low (when the temperature on the ground is less than 0 ° C, even if the temperature on the ground is 0 ° C or higher, it is 1500 m above the sky and below -6 ° C or 5500 m above the ground- It is also known to bring heavy snow (heavy snow in spring) to the Pacific Ocean side (when the temperature is less than 30 ° C), and a southerly wind called the first spring blows when passing through the Sea of ​​Japan side. Especially in Japan, the flowering of cherry blossoms is closely related to culture, and the declaration of cherry blossoms is issued for each region, and the cherry blossom front moves northward. In countries / regions where daylight saving time is held, the clock will be advanced by one hour from the middle of spring.



As a word, New Year is sometimes used for winter events in the current sense, such as New Year. This is probably because January is spring in the lunar calendar. Partly because of this, the word spring may have the meaning of "beginning of things, beginning of the new year." Even in the West, the Italian word "Primavera" and the French word "Printemps"
