Solstice vs. Equinox: What Is the Difference?
A solstice and an equinox are both important astronomical events, but they are not the same.
A solstice occurs when one hemisphere experiences its longest or shortest day of the year.
An equinox occurs when day and night are approximately equal in length.
Simple Comparison
- Solstice: Longest or shortest daylight period.
- Equinox: Nearly equal day and night.
The summer and winter solstices mark the two extreme points of annual daylight. The spring and autumn equinoxes mark periods of nearly balanced daylight and darkness.
Summer Solstice and Winter Solstice
Summer Solstice
The summer solstice is the longest day of the year in a particular hemisphere. It occurs when that hemisphere is tilted most toward the Sun.
For example, the June solstice is the summer solstice in the Northern Hemisphere.
Winter Solstice
The winter solstice is the shortest day of the year in a particular hemisphere. It occurs when that hemisphere is tilted farthest away from the Sun.
For example, the December solstice is the winter solstice in the Northern Hemisphere.
Because the seasons are opposite in the two hemispheres, a summer solstice in one hemisphere occurs at the same time as a winter solstice in the other.
