6 Seasons
A season is a part of a year that is determined on the basis of a specific universal formula. The seasons of the year are usually divided based on the local weather. In most countries of the world, spring, summer, autumn, and winter are the four main seasons. The people of some countries have further divided the seasons into several parts. There are 6 seasons in the northern states including Bangladesh, India, and Australia.
Biodiversity
The seasons are determined by changes in weather, biodiversity, and daylight. Besides, the annual rotation of the earth around the sun is related to the change of seasons. Seasons play an important role in biodiversity. Flowers bloom especially in spring; Hedgehogs sleep in the winter and we soon realize that the season has been changed.
Regionally
There are two seasons in the tropics. Rainy season and Dry season. Besides, there are two seasons in the winter area. Polar Day (spring and summer) and Polar Night (autumn and winter).

Bangladesh
Seasons in Bangladesh are divided into 6 seasons based on weather and climate. Namely: summer, rainy season, autumn, late autumn, winter, and spring. Each season has its own unique characteristics. Although the periods of all the seasons are not the same, the calendar year is divided into several seasons of the same periods for the convenience of calculation. For example, in Bangladesh, the duration of each of the six seasons is two months which is around 60 days.
India
Due to its location in a huge geographical area, India has a diverse climate. According to the Koppen climate classification, there are six major meteorological sub-classes in India. For example, deserts in the west, alpine tundra and glaciers in the north, tropical wetlands in the southwest and islands. In some areas, different local climates are also observed. There are four major seasons in the country. Among them - winter (January-February), summer (March to May), monsoon (June to September) and autumn (October to December).
Count
Seasons are determined by mainly temperature and other characteristics due to weather conditions. Here summer is considered the hottest time of the year on a quarterly basis and winter is considered the coldest time of the year on a quarterly basis. According to this calculation, the Roman calendar has started and the spring season has been observed from March 1. Also, each season consists of 3 months. In 1780, the ancient meteorological organization "Societas Meteorologica Palatina" identified three full months as seasons. Since then, professional meteorologists around the world have used this definition as a model.
