Seasons shape what we eat, how we work, where we travel, and even how cultures mark the year. But “when” seasons start depends on which definition you use — astronomical, meteorological, or cultural — and on where you are on Earth. This post explains each system, why they differ, and what those differences mean for weather, ecosystems, culture, and everyday life.
Starts between March 19 and March 21 ; ends between June 20 and June 22 .
Starts between September 21 and September 23 ; ends between December 20 and December 23 . when do the four seasons start and end
Understanding when the four seasons start and end can help us appreciate the beauty and rhythms of nature. Whether you're in the Northern or Southern Hemisphere, we hope this guide has been helpful in planning your activities and staying connected to the world around you.
The truth is that there are two widely accepted ways to define the seasons: (based on the Earth’s orbit around the sun) and Meteorological (based on the annual temperature cycle and the calendar). A third, less common method involves the solar calendar used in various cultural traditions. Seasons shape what we eat, how we work,
The confusion is understandable. There isn't just one universal answer to the question, In fact, scientists, meteorologists, and astronomers use two very different systems to define the seasons.
Starts at the December Solstice ( December 20–23 ) and ends at the March Equinox ( March 19–21 ). Starts between March 19 and March 21 ;
Whether you rely on the precise geometry of the astronomical solstices or the streamlined simplicity of the meteorological calendar, the shifting seasons remain a universal marker of time, driving the rhythms of ecology, agriculture, and human culture across the globe.

(Exact hour/minute changes every year; consult an astronomical almanac for precise timestamps.)
However, scientists have observed a phenomenon called Over the past 50 years:
June 21 – September 22
