Spring is 30 seconds shorter every year

Shortening of spring each year is due to the way Earth's axis wobbles as it moves - but most of us won't notice the difference in our lifetime

Every year spring is getting shorter by about 30 seconds, according to researchers.

This is mainly to do with how the Earth's axis wobbles - very slowly - as it moves, or as LiveScience explains, "like a wobbling top, in a type of motion called precession".
