Why Spring Gets About 30 Seconds Shorter Every Year

Prepare for a spring that is about 30 seconds shorter than last year’s, which was 30 seconds shorter than the one before. The changing length of the season is related to the tilt of the Earth’s axis, LiveScience reports. In fact, spring and winter get shorter, while summer and autumn get correspondingly longer.

The summer solstice occurs when the northern hemisphere is most tilted toward the sun. Spring ends at the summer solstice, and because of precession, the point along the Earth’s orbit where the planet reaches the summer solstice shifts slightly. Next year, the planet will reach the point in its orbit of the solstice slightly earlier.

The shortening-spring trend won’t last forever: Around the year 8680, the season will be at its shortest, at 88.5 days. After that, spring will start getting longer again.

I can barely wait…
