SUN RISE(DUSK)2024 The sunrise is a breathtakingly beautiful phenomenon that marks the beginning of a new day. As the sky lightens the stars fade away, and the moon dips below the horizon, the sun slowly rises above the clouds, painting the sky with hues of pink, orange, and purple. the gentle warmth of the sun’s rays spreads across the land, awakening the word form its slumber.
The timing of sunrise varies throughout the year and is also affected by the viewer’s latitude and longitude, altitude, and time zone. These changes are driven by the axial tilt of Earth, daily rotation of the Earth, the planet’s movement in its annual elliptical orbit around the Sun, and the Earth and Moon’s paired revolutions around each other. The analemma can be used to make approximate predictions of the time of sunrise.
In late winter and spring, sunrise as seen from temperate latitudes occurs earlier each day, reaching its earliest time near the summer solstice; although the exact date varies by latitude. After this point, the time of sunrise gets later each day, reaching its latest sometime around the winter solstice. The offset between the dates of the solstice and the earliest or latest sunrise time is caused by the eccentricity of Earth’s orbit and the tilt of its axis, and is described by the analemma, which can be used to predict the dates.
Variations in atmospheric refraction can alter the time of sunrise by changing its apparent position. Near the poles, the time-of-day variation is exaggerated, since the Sun crosses the horizon at a very shallow angle and thus rises more slowly.[1]
Accounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night. The sunrise equation, however, which is used to derive the time of sunrise and sunset, uses the Sun’s physical center for calculation, neglecting atmospheric refraction and the non-zero angle subtended by the solar disc.

Neglecting the effects of refraction and the Sun’s non-zero size, whenever sunrise occurs, in temperate regions it is always in the northeast quadrant from the March equinox to the September equinox and in the southeast quadrant from the September equinox to the March equinox.[6] Sunrises occur approximately due east on the March and September equino
The first sunrise refers to the custom of observing the first sunrise of the year. Such a custom may be just an observation of the sunrise on a special day, or has a religious meaning for those who worship the Sun, such as the followers of traditional religions in Korea and Japan and the Inuit, Yupik, Aleut, Chukchi and the Iñupiat in the Arctic Circle, for praying for good luck.
Japan
In Japan, the observation of the first sunrise of the year (Japanese: 初日の出, romanized: Hatsu-Hinode) on the first day on the Old Calendar has been part of the traditional Shintoist worship of Amaterasu, the sun goddess.[1] Nowadays, Japanese travel agents arrange trips to observe the earliest first sunrise of the year on the new Gregorian calendar in the easternmost Ogasawara Islands of the Japanese archipelago.
Mongolia
In Mongolia, there is a custom of observing the first sunrise on the first day of the year at the top of the mountain the Mongolian lunisolar calendar. commonly known as Tsagaan Sar. The holiday has shamanistic influences.[2][3]
Korea
In Korea, there is also a custom of observing the first sunrise on the first day of the year, either on the traditional Korean calendar or the new calendar.[4]
Canada, Greenland, Russia and the United States
In the Arctic circle, the Inuit, Yupik, Aleut, Chukchi and the Iñupiat observe the first sunrise on the first day of the year (Inuktitut: ᓯᕗᓪᓕᖅᐹᒥ ᓯᕿᓂᖅ ᓴᖅᑭᑎᓪᓗᒍ ᐊᕐᕌᒍᒥ) by extinguishing three qulliqs and relighting them.[5][6] This is to honor the sun and moon.
