This year, Spring officially begins on 20th March in the northern hemisphere. Here are some interesting facts about Spring time..

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.

In some cultures in the Northern Hemisphere (e.g. Germany), the astronomical vernal equinox (varying between 19 and 21 March) is taken to mark the first day of spring, and the summer solstice (around 21 June) is taken as the first day of summer. In Persian culture the first day of spring is the first day of the first month (called Farvardin) which begins on 20 or 21 March. In other traditions, the equinox is taken as mid-spring.

In the traditional Chinese calendar, the "spring" season consists of the days between Lichun(February 3–5), taking Chunfen (March 20th-22nd) as its midpoint, then ending at Lixia (May 5–7). Similarly, according to the Celtic tradition, which is based solely on daylight and the strength of the noon sun, spring begins in early February (near Imbolc or Candlemas) and continues until early May (Beltane).

The beginning of spring is not always determined by fixed calendar dates. The phenological or ecological definition of spring relates to biological indicators, such as the blossoming of a range of plant species, the activities of animals, and the special smell of soil that has reached the temperature for micro flora to flourish. These indicators, along with the beginning of spring, vary according to the local climate and according to the specific weather of a particular year. Most ecologists divide the year into six seasons that have no fixed dates. In addition to spring, ecological reckoning identifies an earlier separate prevernal (early or pre-spring) season between the hibernal (winter) and vernal (spring) seasons. his is a time when only the hardiest flowers like the crocus are in bloom, sometimes while there is still some snowcover on the ground.

n recent decades, season creep has been observed, which means that many phenological signs of spring are occurring earlier in many regions by around two days per decade.

Spring in the Southern Hemisphere is different in several significant ways to that of the Northern Hemisphere for several reasons, including:

    There is no land bridge between Southern Hemisphere countries and the Antarctic zone capable of bringing in cold air without the temperature-mitigating effects of extensive tracts of water;

    The vastly greater amount of ocean in the Southern Hemisphere at most latitudes;

    At this time in Earth's geologic history the Earth has an orbit which brings it in closer to the Southern Hemisphere for its warmer seasons;

    There is a circumpolar flow of air (the roaring 40s and 50s) uninterrupted by large land masses;

    No equivalent jet streams;

    The peculiarities of the reversing ocean currents in the Pacific.

And of course Easter falls during Spring time - enjoy your Easter eggs!
