The Full Moon is one of the four main phases of the Moon. It occurs when the Sun, the Earth and the Moon are approximately aligned, and the Moon and the Sun are on opposite sides of the Earth. In this arrangement the entire sunlit part of the Moon faces us. A Full Moon is sometimes called a “Supermoon” when the Moon is at its closest distance from Earth, as it then appears bigger and brighter than usual.

In 2026, the March equinox falls on 20 March. In the northern hemisphere, after the March equinox, daylight hours start to be longer, and it's thus considered as the beginning of the season of Spring.
