Earth's axis is tilted,so the angle at which the sun's rays strike the earth changes from month to month.This tilt along with the orbital motion of the earth around the sun causes the seasons. During the summer season in the northern hemisphere ,the northern side of the earth's axis is tilted towards the sun and the southern hemisphere is tilted away from the sun. During the northern hemisphere winter,the northern hemisphere tilts away from the sun and the southern hemisphere towards it. According to astronomical calender,the seasons begin at specific points known as the solstices and equinoxes,along earth's orbit around the sun. The solstices are the two days-June 21 and December 21- when the sun is directly over one or other tropic(Tropic of cancer or Tropic of capricon) producing the maximum and minimum daylengths.On these two days the equator is at its farthest point from the sun. The equinoxes(meaning day and night of equall length) occur when the sun is directly overhead at the equator on March 21 and September 22. The greatest changes in heat and light ocur in mid and high latitudes and these regions have four seasons.'Fall' strarts at the autumnal equinox(21 st March),'Spring' at the vernal equinox(September 22), 'Winter' at winter solstice(December 22) and'Summer' at summer solstice(June 21). Between the tropic of cancer and capricon,the sun shine overhead producing convection and maximum storm activity.As this spot shifts between the two tropics,heavy rainfall moves too,giving a cycle of only two seasons,wet and dry. At the equator,there is only one season.

Why do Australian seasonsstart on the 1st of the month?
Australians start the change of season on the 1st of the month. Summer 1st December, Autumn 1st March, Winter 1st June, Spring 1st September. Many countries (especially Northern hemisphere) start their seasons on the equinox or solstice dates. Why is Australia different? Did we ever have our seasons dates start mid-month or did the First Fleet dictate the 1st of the month? If we started mid-month when did it change to the 1st of the month?
In countries such as the UK, Denmark, Ireland and Australia the seasons are simply decided according to the Roman calendar, with the seasons decided by the hottest / coldest quarters of the year and beginning on the first of the month. So Autumn - March 1st Winter - June 1st Spring - September 1st Summer December 1st and reverse for the opposite hemisphere. For countries such as the United States, the seasons are determined Astrologically - and begin at the solstice and equinoxes. So spring begins when the days hit equal length then get longer, autumn when they hit equal length then get shorter etc. Thus spring - March 19 - 22 - the spring equinox Summer - 19 - 23 June - the summer solstice Autumn - 21 - 24 Sept - the autumn equinox Winter 20 - 23 Dec - the winter solstice and vice versa for the opposite hemispheres. Since the idea of four seasons was imposed on the rest of the world by northern Europeans and north Americans, there has been dispute about the start of the seasons. Most countries that subscribe to the four season idiocy start them on the solstices and equinoxes. Australia starts them on the first of the month. My investigations have found a possible reason for this although it could well be apocryphal. The NSW Corps changed from its summer to winter uniform on the first of March and from its winter to its summer uniform on the first of September. The starting dates for the other seasons followed this. It is much easier for record keeping if the seasons start on the first of the month rather than an arbitrary date between the 20th and 23rd. The Bureau of Meteorology certainly likes starting the seasons on the first. Seasons were named and identified long before anyone knew that the Earth revolved on its axis, that the axis was tilted or that the earth orbioted the sun. They were identified from the behaviour of animals and plants and from the weather. Northern Europe settled on four seasons. In Australia, there are five named and identified seasons in the Kimberley, six in the Darwin/Kakadu area and the Wik people of Cape York have eight. Each of these is just as valid as the northern European four.
