What is the date of the last day of spring 2010?

Answer 1

Depends on whether you're in the Northern Hemisphere or Southern Hemisphere.

In the northern hemisphere, the last day of Spring is 31 May (no matter what year it is).

In the Southern Hemisphere, it's 31 November (no matter what year it is).

Answer 2

In the Northern Hemisphere, the last day of winter is March 19, 2010, and the Vernal Equinox (first day of Spring) is March 20, 2010.

In the Southern Hemisphere, the last day of winter will be September 22, 2010.

Answer 3

Northern Hemisphere:

Saturday, March 20, 2010, was the official first day of spring for 2010 in the Northern Hemisphere. The Vernal Equinox occurred at 17:32 UTC. On that day, the Southern Hemisphere observed the Autumnal Equinox, which is the equivalent of the start of Autumn.

Southern Hemisphere

The official date of spring south of the equator (corresponding to the first official day of fall in places north of the equator) was September 23, 2010. (03:09 UTC)

Countries such as Australia and New Zealand, however, designate the first day of September as the official first day of spring.

In general, the four seasons correspond to the relative position of the sun to the earth. Meteorological determination of spring is calculated according to when the sun passes through the equatorial plane. When going from winter to spring, the sun is moving north; as soon as the sun crosses the equator, we call it spring. (This applies to places north of the equator.)

Spring arrives in the Northern Hemisphere between the 19th and 23rd of March and at various local times. It changes on a yearly basis because the first official day of spring is the (Spring) Vernal Equinox. This is when the Sun is directly above the equator. It rises due East and sets due West and does not do so on the exact same day every year; this is because the year is not exactly 365 days as the calendar is.
March 20
Saturday March 20, 2010 is the first day of spring.
