only 1 day.....Another AnswerTwo days: Autumn equinox and Spring equinox.
The Equinox (Vernal & Autumnal) There are only two times of the year when the Earth's axis is tilted neither toward nor away from the sun, resulting in a "nearly" equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes
Astronomical seasons are spring, summer, autumn, winter. Ecological seasons are prevernal (pre-spring thaw), vernal (spring growing season), estival (high summer), serotinal (late summer), autumnal (fall), and hibernal (winter).
116 days.Winter always begins on December 21st. Based on today's date of August 27, 2010, there are exactly 116 days left until that date.Remember, to find out how long it is until winter, always count the amount of days from the current date to December 21.

3 Twice. On the Autumnal equinox and on the Vernal equinox.
Equinox
liedlihqwlkhdaLDHLISHLSAD'S Equinoxes occur four times a year. The Vernal Equinox occurs in March, the Summer Solstice occurs in June, the Autumn Equinox occurs in September, and the Winter Solstice occurs in December.
In 2008, spring, as defined as the period from the vernal equinox to the summer solstice, lasted 92 days, 18 hours and 11 minutes.
365.25 days. If you want a more exact answer you have to specify whether you mean the vernal equinox year, the sidereal year or the tropical year.
22nd September is the beginning of Spring in the Southern Hemisphere but the beginning of Autumn ["Fall" in ther USA] in the Northern Hemisphere. 22nd April is the beginning of Autumn in the Southern Hemisphere but the beginning of Spring in the Northern Hemisphere. 22nd June is the beginning of Winter in the Southern Hemisphere but the beginning of Summer in the Northern Hemisphere. 22nd December is the beginning of Summer in the Southern Hemisphere but the beginning of Winter in the Northern Hemisphere.
Twice, at the Summer and Winter Solstaces.
I do not go by the number of days but in a 360 degree year there are 60 degrees between the Autumnal Equinox and the Vernal Equinox. or you must count the days in each month in a sidereal calender instead of the lunar one that I go by for a few reasons/keeping track of my cycle for one reason and my sanity for another. > Just ME<
Thee are 2 dates for the start of spring in the northern hemisphere in 2018. March 1st is the meteorological date but the vernal equinox, when day and night are the same length, is March 20th.
When night and day are approximately of equal length occurs twice per year. In the northern hemisphere these days are called the Vernal Equinox (20-21 March) and the Autumnal Equinox (22-23 September). However, as these seasons are reversed in the southern hemisphere, current usage is the March Equinox and the September Equinox.
There are two equinoxes (i.e. vernal/spring and autumnal/fall) every year.
