The spring equinox marks the start of astronomical spring. The date is determined by the Earth's tilt on its axis as it travels around the Sun. At the equinox, the Earth's axis is tilted neither towards nor away from the Sun, making day and night nearly equal in length. The equinox happens twice a year - in March and in September.

The vernal equinox heralds the arrival of spring in the Northern Hemisphere (finally). But have you heard the myth about balancing an egg on its end?
