By the meteorological calendar, spring will always start on 1 March; ending on 31 May.
Spring is the season after winter and before summer. Days become longer and weather gets warmer in the temperate zone because the Earth tilts relative to its orbital plane around the Sun. In many parts of the world it rains for hours. This helps the plants grow and flowers bloom
Spring and "springtime" refer to the season, and also to ideas of rebirth, rejuvenation, renewal, resurrection and regrowth. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, monsoonal or cyclonic. Cultures may have local names for seasons which have little equivalence to the terms originating in Europe.
During early spring, the axis of the Earth is increasing its tilt relative to the Sun, and the length of daylight rapidly increases for the relevant hemisphere. The hemisphere begins to warm significantly, causing new plant growth to "spring forth", giving the season its name
