Where a season falls depends on where sunlight hits the Earth’s 23.5-degree axis tilt.
Unlike meteorological seasons, those picked using astronomical methods often differ in length every year.
As such, they often fall on different dates, but this is not the case in 2021.
Spring is an equinox, and in 2021 falls on March 20, the same day as it did last year.
The season then lasts for just over three months until June 21 this year.
