Night and Day

There are many physical and obvious differences between day and night, but there are many nuances in human behavior during the day compared to white night. People's behaviors differ mainly between day and night, mainly due to fear, lack of censorship and judgment, and liberation from duty. During the day, the sun illuminates the whole world and draws everything in a clear sight, but at night, the moon will shine a faint shine, the world can be blurred, pushed by shadows and darkness.

When the earth rotates around its axis, we make day and night on the earth. The sun rises in the east, descends to the west, and night becomes night. On the earth, the length of the day and night usually varies according to the season. Why is the season different? As mentioned earlier, the Earth rotates around the tilt axis approximately every 24 hours, creating the day and night we know. The axis is an invisible line passing through the center of the earth. North Point as North Pole, South Point as South Pole

As the earth rotates around its axis regardless of day and night, the Earth moves around the sun with an elliptical (thin circular) orbit, which takes 1/4 days 365 days. The axis of the earth is tilted 23.5 degrees. When the axis of the earth is facing the sun, its hemisphere is summer. When the axis of the earth is facing far, winter is expected. The sun always rises in the east and the west, so you can judge the time by looking at the position of the sun. Looking at the east, the sun is on the horizon. In other words, it is around 6 AM. When the sun is right above your head it means noon. Looking at the west, the sun is on the horizon. In other words, it is around 6 PM.

Spring Equinox is another important day when the earth travels around the sun. Recently, the axis of the planet is oriented parallel to the sun, but it is neither towards the sun nor away from the sun. The day and night between vernal equinox should be equal. The spring or spring equinox of the Northern Hemisphere occurs about March 20th the same as the South East. The vernal equinox of the southern hemisphere occurred around September 20th when the northern hemisphere celebrates the fall dividing point. The vernal equinox is the first day of the hemisphere Astronomy Spring and the first day of the autumn equinox welcomes the fall dividing point

At the vernal equinox point, the day and night are about 12 hours each. (In the northern hemisphere, the actual time hours before the vernal equinox is the same for the day and night.) The sun moves north across the equator of heaven; it rises completely to the right east and is exactly right west. Please check the first day of the spring page. During the summer solstice, we enjoy the most white year of the calendar year. The sun reaches the northernmost tip of the sky (northern hemisphere) at noon local time. From this date on, the date will begin to "shorten". In other words, the length of sunlight will begin to decline. Please check the first summer page.
