September
The answer is Southern Hemisphere.
It is in the Southern Hemisphere
No. The Sun is always above the horizon somewhere in the Southern hemisphere just as it always is above the horizon somewhere in the Northern hemisphere. About half of each hemisphere is illuminated at every instant (well more of the Southern hemisphere is illuminated from the end of September to the end of March and more of the Northern hemisphere during the other half year).
The vernal equinox is the first day of spring (occurring when the North Pole begins to lean toward the sun). The autumnal equinox is the first day of autumn (occurring when the North Pole leans away from the sun).
September
It depends. If you are in the Northern Hemisphere it is March. If you are in the Southern Hemisphere it is September.
The first official day of Spring in the entire northern hemisphere is March 22nd. Because of the tilt in the Earth's axis, the first day of spring in the southern hemisphere is September 22nd.
The first day of spring in the Southern Hemisphere is September 21. Antarctica is located in the Southern Hemisphere.
Not just Australia, the whole of the Southern Hemisphere. In the Southern Hemisphere, the Winter Solstice is on the 21st of June, the Summer Solstice is on the 21st of December. The Spring Equinox is on the 21st of September, and the Autumn Equinox is on the 21st of March. Therefore, Spring commences on the 1st of September in the whole of the Southern Hemisphere. Unfortunately, because the earth is viewed inaccurately from a Northern Hemisphere perspective, the Southern Spring Equinox is actually referred to as the "Autumnal Equinox" so that it does not confuse the northerners.
In the northern hemisphere, the first day of Spring in 2016 is on 20 April, while in the year 2023 it is on 21 March. In the southern hemisphere, the first day of Spring is always 1 September, and not on the vernal equinox.
The first day of winter everywhere in the Southern Hemisphere is June 21 and the first day of spring is September 21.
The first day of winter everywhere in the southern hemisphere is June 21. The first day of spring is September 21.
In 1971, spring began on 21st March at 6:38 AM UTC in the northern hemisphere and on 23rd September at 4:45 PM UTC in the southern hemisphere.
The first day of spring coincides with the equinox (days and nights both 12 hours long). In the northern hemisphere the equinox is around the end of March. In the southern hemisphere it starts about the beginning of September. In the US the first day of Spring will be March 20, 2010. In Australia, the first day of Spring will be 1 September 2010.
