What day has 12 hours of daylight and 12 hours of darkness?
September Equinox (Approximately September 22-23)
There are 12 hours of daylight and 12 hours of darkness at all points on the earth's surface on the two equinoxes. Sunrise is at 6 a.m. and sunset is at 6 p.m. local (solar) time for most points on the earth's surface.
What means equal day and night?
The word equinox is derived from the Latin words aequus (equal) and nox (night). It means equal day and night. But in reality, the day is longer than the night at an equinox.
In which country day and night are equal?
The equator receives equal night and day. Since the equator stays in the same place relative to the sun, the level of sunlight received throughout the year is nearly constant.
At the equator, the sun is directly overhead at noon on these two equinoxes. The "nearly" equal hours of day and night is due to refraction of sunlight or a bending of the light's rays that causes the sun to appear above the horizon when the actual position of the sun is below the horizon.
Ever wondered where in the world is the first place to see the sun rise? Well, wonder no longer! North of Gisborne, New Zealand, around the coast to Opotiki and inland to Te Urewera National Park, The East Cape has the honour of witnessing the world's first sunrise each and every day.
Antarctica has six months of daylight in its summer and six months of darkness in its winter. The seasons are caused by the tilt of Earth's axis in relation to the sun. The direction of the tilt never changes.
In Svalbard, Norway, which is the northern-most inhabited region of Europe, the sun shines continuously from April 10 to August 23. Visit the region and live for days, for there is no night. Don't forget to get a peek of the northern lights when visiting.
The event, known as equinox, is eagerly awaited by space enthusiasts as it takes place only twice a year, on March 21 and September 23.
Due to Autumn Equinox, the equator of the Earth falls exactly in front of the Sun on 21 March and 23 September. Due to which the time of day and night becomes equal. Due to this, the situation of Equinox is being created on Thursday, 23 September 2021, Equinox is a Latin language word, which means the same night.
winter solstice, also called hibernal solstice, the two moments during the year when the path of the Sun in the sky is farthest south in the Northern Hemisphere (December 21 or 22) and farthest north in the Southern Hemisphere (June 20 or 21).
The morning twilight is often called dawn, while the evening twilight is also known as dusk.
In 2021 the winter solstice will occur on Tuesday 21 December. The winter solstice occurs in December, and in the northern hemisphere the date marks the 24-hour period with the fewest daylight hours of the year. That is why it is known as the shortest day of the year, or the longest night of the year.
Daylight hours on the solstice
The Northern Hemisphere sees its shortest day of the year on Dec. 21, but the amount of daylight depends on how far you live from the equator.
The longest day of 2021 for those living north of the Equator is June 21. In technical terms, this day is referred to as the summer solstice, the longest day of the summer season. It occurs when the sun is directly over the Tropic of Cancer, or more specifically right over 23.5 degree north latitude.
Today, June 21 is the Summer Solstice, which is the longest day of the summer season and takes place in the northern hemisphere when the Sun is directly over the Tropic of Cancer. Summer Solstice signals the start of the summer season in the northern hemisphere and the beginning of winter in the southern hemisphere.
The reason for this is because Earth is tilted 23.5 degrees away from its axis of rotation. If there were no tilt, everywhere on Earth would receive 12 hours of daylight and 12 hours of night every day, regardless of how close or far to the Equator.
Dong village in Arunachal Pradesh, which is known as the easternmost village in India, witness the earliest sunrise in the country. At about 1,240 metres above sea-level, Dong is located between China and Myanmar.
Samoa! As you may know the international date line is as crooked as the contents of a badly packed suitcase, and Samoa, once known as the last place to see the sun set, is now the first place on the planet you can see the sun rise. This makes it's neighbour American Samoa the last.
Japan is known as the “Land of Rising Sun”. It is called by this name because the sun rises first in Japan and then in any other part of the world. Japan has one of the highest advanced technologies. Tokyo is the capital of this beautiful country.
Here's what I learned about happiness and the wintertime blues. Located more than 200 miles north of the Arctic Circle, Tromsø, Norway, is home to extreme light variation between seasons. During the Polar Night, which lasts from November to January, the sun doesn't rise at all.
Spring in the Norwegian arctic seems to spend a long time plotting its annual comeback. When it returns, though, it does not disappoint.
Antarctica is the only continent with no permanent human habitation. There are, however, permanent human settlements, where scientists and support staff live for part of the year on a rotating basis.

Nauru, an island in the Pacific Ocean, is the second-smallest republic in the world—but it doesn't even have a capital city.
The 40-minute night in Norway takes place in June 21 situation. At this time, the entire part of the earth from 66 degree north latitude to 90 degree north latitude remains under sunlight and this the reason why the sun sets for only 40 minutes. Hammerfest is a very beautiful place.
In Svalbard, Norway, the northernmost inhabited region of Europe, there is no sunset from approximately 19 April to 23 August. The extreme sites are the poles, where the Sun can be continuously visible for half the year. The North Pole has midnight sun for 6 months from late March to late September.
Answer: Days and nights are equal at all places on earth on March 21 because on this day sun rays will fall in the vertical direction towards the equator or at the center position of the earth. This supplies the equal light distribution from pole to pole which makes the day and night duration same.

So, at the end of the day, while solstices and equinoxes are related, they happen at different times of the year. Just remember that solstices are the longest and shortest days of the year, while equinoxes occur when the day and night are equally as long.
Why Is It Called Equinox? Equinoxes represent an equal length of day and night occurring simultaneously for an ideal 12 hours each. It is for this reason that it is termed equinox. The word can be broken down into 'equi,' meaning equal, and 'nox,' meaning night.
The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.
Winter Solstice – The Longest Night of the Year. On the 21st of December, the Northern Hemisphere will sink into its deepest point of darkness. Have no fear, it is only the longest night and the shortest day of the year. Today, those of us in the north will be basking in roughly eight hours of daylight.
It is on June 21 that the calendar shows the longest night in the year and the winter solstice takes place in the southern hemisphere.
At 6:12 a.m. EST on Friday (Dec. 21), the sun will reach a point where it will appear to shine farthest to the south of the equator, over the Tropic of Capricorn, thus marking the moment of the winter solstice — the beginning of winter. Most cultures had winter solstice celebrations and some adapted it to other events.
(Sunset can be defined as the moment when the top of the sun's disk has passed the horizon.) As with twilight, there is civil dusk, nautical dusk, and astronomical dusk, occurring at the exact moment when the center of the sun's disk is at 6°, 12°, and 18° below the horizon, respectively.
In its most general sense, twilight is the period of time before sunrise and after sunset, in which the atmosphere is partially illuminated by the sun, being neither totally dark or completely lit.
