The cycle of the four seasons—spring, summer, fall (autumn), and winter—is a fascinating aspect of Earth’s journey around the sun. Each season has its own unique characteristics, offering us different experiences throughout the year. But how long does each season last? Let’s break it down in terms of weeks.
The length of each season is determined by the Earth’s orbit around the sun and the tilt of its axis. The year is divided into four seasons based on astronomical events:
- Spring Equinox: Around March 20-21
- Summer Solstice: Around June 20-21
- Fall Equinox: Around September 22-23
- Winter Solstice: Around December 21-22
Average Duration of Each Season
On average, the length of each season is as follows:
- Spring: Approximately 13 weeks (91 days)
- Summer: Approximately 13 weeks (93 days)
- Fall: Approximately 13 weeks (90 days)
- Winter: Approximately 13 weeks (89 days)
While astronomical seasons are based on specific solar events, meteorological seasons divide the year into four equal parts for ease of comparison and record-keeping:
- Spring: March 1 to May 31
- Summer: June 1 to August 31
- Fall: September 1 to November 30
- Winter: December 1 to February 28 (or 29 in a leap year)
