Lunar day

The day of the month is the period in which the moon on the earth completes its rotation on its axis against the sun. It is also when the moon rose around the Earth and returned to the same stage because of the tide lock. The month of the month is the period between two new months, followed by about 29.5 sun days

Compared to stars on the celestial sphere, the moon needs 27 earth days, 7 hours, 43 minutes, 12 seconds to complete the orbit [1] But the Earth and Moon system will move around the sun at the same time So the moon will go on to the same stage further. On average, this desired period lasts 29 days, 12 hours, 44 minutes, 3 seconds. [1] This is average. The speed of the Earth's moon system around the sun changes slightly within a year due to the eccentricity of the elliptical orbit, the change in orbital velocity, and the relative periodicity of the observations. Changes in evolutionary change, gravity disturbance within the solar system and other objects in the solar system

Therefore, sunlight at a particular point in the moon lasts about two weeks from start to finish, then about two weeks of the night.

The term Moon Day may also refer to the period between the Moon or Takatsuki in a particular place on the Earth. Because the moon circles the earth in the same direction as the axis rotation of the earth, this period is about 50 minutes longer than the day of the earth, usually 24 hours. [2]

In contrast to Lunar New Year, the term Lunar Day is used regardless of day or night. This is common in discussions on major temperature differences, such as discussion of moon explorers. "The mission of the moon of the Soviet Union was to survive in the calendar of the month (2 earth weeks). [3]

In some monthly calendars like Hindu calendar, month calendar, or tichi, it is necessary to increase the longitudinal angle between 1/30 of the moon's moon or between the moon and the sun by 12 degrees Time. According to this definition, the lunar calendar period is usually different.

Shredda was run in a specific lunar calendar between Pitru Paksha when the ancestors - usually parents and grandparents - died. There are exceptions to the lunar calendar rule; special days are assigned to those who die in a special way or have a certain position in life. Last year, the fourth and fifth lunar calendars Chautha Bharani and Bharani Panchami died. Avidhava navami ("Unwidowed nine") in September is suitable for married women who died in front of their husbands. W couple invited Brahmin women as guests of their wife shraddha. The 12th day of the lunar calendar is for children and abstinence who abandon the fun of the world. Day 14 is called Ghata chaturdashi or Ghayala chaturdashi which is reserved for people killed by weapons, war or violence.

In contrast to Lunar New Year, the term Lunar Day is used regardless of day or night. This is common to be seen in discussions of major temperature differences like moon explorer debates.

Temperatures in the daytime on the moon exceed 100 ° C, temperatures in the night may fall to -180 ° C. You can supply electricity to lunar colony of the lunar calendar using solar panels, but during the night of the moon - equivalent to 14 Earth days - supplying power to the colony needs to be dealt with It is a problem. As in the area of ​​eternal light, there is a permanent area in the dark near the poles. This is usually due to the fact that the peaks obscure the area of ​​deep craters where sunlight or sunlight can not reach. NASA's Moon Scout Orbiter (LRO) observes these shaded areas of Antarctica

The month of the month is divided into 30th lunar calendar calendar. The day of the calendar month in India is called Titty. They are also very scientifically calculated by the difference in the vertical angle between the sun and the moon position. Each TITTI is defined by the time it takes for the longitude of the moon to increase by 12 ° with the longitude of the sun. Vedic astronomers know that the orbit of the moon around the earth is elliptical and count the days of each month 's day (or titi). Titi's length varies from about 20 hours to about 27 hours. That is why we sometimes found Titi "omitted" and in some respect shared the same Titty for two consecutive days.
