The spring equinox occurs when the sun crosses the celestial equator moving northward, producing roughly equal hours of daylight and darkness. In the UK it falls around 20 March each year. This is the astronomical start of spring, distinct from the meteorological start on 1 March. After the equinox, days become longer than nights until the summer solstice in June. The equinox has been marked at ancient sites including Stonehenge for thousands of years.
