When is spring in 2014?

Answer 1

First Day of Spring was on March 20, 2011 and the last day of Spring was on June 20, 2011.Astronomical spring in the Northern Hemisphere as defined by the International Astronomical Union begins with the Vernal Equinox on March 20, 2011, at 7:21 p.m. EDT.

At the start of spring (spring equinox), day and night are approximately 12 hours long (at the equatorial plane) and the Sun is at the midpoint of the sky. Our north pole tilts towards the Sun.

NOTE-"the north pole tilts toward the sun." that is true on summer solstice, but in December the south pole tilts toward the sun. At the equinoxes the tilt is parallel to the sun.

First day of spring in the Northern Hemisphere

In general, the four seasons correspond to the relative position of the sun to the earth. Astronomical 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.)

First day of spring in the Southern Hemisphere

The "official" date of spring south of the equator (official is corresponding to the first day of fall in places north of the equator) would be around September 20/21, depending on when the sun crosses the equator.

Countries such as Australia and New Zealand, however, designate the first day of September as the official first day of spring (climatological counterpart). Preference between these two methods varies across Europe. Many east Asian countries use lunar dates to determine the beginning of spring.

In Addition

The climatological spring as defined by the World Meteorological Organization began on March 1, 2011.

The ecological spring begins locally with the beginning of the growing season. Usually in temperate climates when the mean daily temperature reaches 6 degrees C/42 degrees F. This can be as early as February in mild climates. and as late as April or May in cool climates.
Spring starts on March 21st .

Answer 2

First Day of Astronomical Spring is on March 19/20, 2012

Astronomical spring in the northern hemisphere, as defined by the International Astronomical Union, begins with the Vernal Equinox on March 20, 2012, at 1:14 am EST. The equinox falls in the later hours of March 19 in the Mountain, Pacific and Alaska time zones of North America and across the Pacific Ocean between 120 degrees west longitude and the international date line. In the southern hemisphere, astronomical spring begins on September 23, 2012 in New Zealand, parts of Australia and Papua New Guinea and in the South Pacific west of the international date line and September 22 everywhere else.

At the start of the astronomical spring (spring equinox), day and night are approximately 12 hours long (at the equatorial plane) and the Sun is at the midpoint of the sky. Our north pole tilts towards the Sun.

NOTE: "The north pole tilts towards the Sun." That is true on summer solstice, but in December the south pole tilts towards the Sun. At the equinoxes the tilt is parallel to the Sun.

First Day of Astronomical Spring in the Northern Hemisphere:

In general, the four calendar seasons correspond to the relative position of the Sun to the Earth. Astronomical 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, astronomers call it spring. (This applies to places north of the equator.)

First Day of Astronomical Spring in the Southern Hemisphere:

The astronomical ("official") date of spring south of the equator (corresponding to the first calendar day of fall in places north of the equator) would be around September 19/20, depending on the time zone when the Sun crosses the equator.

First Day of Climatological Spring:

Australia and New Zealand designate the first day of September as the "official" first day of spring. This corresponds to the date used by the World Meteorological Organization to define the climatological spring in the southern hemisphere. In the northern hemisphere, March 1 is the official first day of the climatological spring.

Ecological Spring:

Ecological spring is not a calendar based season, but rather begins locally with the beginning of the growing season when the mean daily temperature reaches 6 degrees C/42 degrees F. This can be as early as February in mild climates and as late as April or May in cool Climates.

Answer 3

Astronomical Spring begins on March 20 and ends on June 21 in 2014.

Astronomical spring in the northern hemisphere, as defined by the International Astronomical Union, begins with the Vernal Equinox on March 20, 2014, at 12:57 pm EST. The equinox falls in the later hours of March 19 in the Mountain, Pacific and Alaska time zones of North America and across the Pacific Ocean between 120 degrees west longitude and the international date line. In the southern hemisphere, astronomical spring begins on September 23, 2012 in New Zealand, parts of Australia and Papua New Guinea and in the South Pacific west of the international date line and September 22 everywhere else.

Astronomical Spring begins on March 20 and ends on June 21 in 2015.

Astronomical spring in the northern hemisphere, as defined by the International Astronomical Union, begins with the Vernal Equinox on March 20, 2014, at 6:45 pm EST.
