Sunrise and sunset schedule every day to see what time the sunset is

The time of sunrise and sunset: in the summer half of the year, the sunrise is before 6 o'clock and the sunset is after 18 o'clock; In winter, the sun rises after 6 o'clock and sets before 6 p.m. Spring and autumn equinox, sunrise at 6 o'clock, sunset at 6 o'clock.

Orientation of sunrise and sunset: except for the polar day.

Outside the polar night, when the sun shines directly in the northern hemisphere, the sun rises in the northeast and sets in the northwest. When the direct point of the sun in the southern hemisphere is, the sunrise is southeast and sunset is southwest. Spring and autumn are equinoxes, rising in the east and falling in the west.

Sunrise time. 12 days long; Sunset time is 12 days long. On the contrary, the length of the day and the length of the night can be calculated according to the sunrise and sunset time of a certain day in a certain place, and the method is as follows:

Day length at a certain place Sunset time Sunrise time (12 noon sunrise time) 2 (Sunset time 12 noon) 2. Somewhere the night is long (midnight.

24 o'clock (sunset time) 2 (sunrise time 0:00 midnight) 2.

The following is the sunrise and sunset schedule in the Beijing area in 2023:

The sunrise and sunset times change throughout the year. Even within the same day, the sunrise and sunset times are different at different latitudes. The earliest day of the year for sunrise is before the summer solstice, the latest day of sunset is after the summer solstice, the earliest day of sunset is before the winter solstice, and the latest day of sunrise is after the winter solstice.

It contains some clever principles of spherical geometry, kinematics, and celestial mechanics.

The time of sunset varies depending on the season and the latitude of each place. Traditionally, in the Northern Hemisphere, the winter solstice has the earliest sunset and the latest sunset is on the summer solstice.

But in reality, the earliest sunset should be in early December, and the latest sunset should be in late June. Even in the equatorial region, the sunrise and sunset times change slightly throughout the year. And these changes can be expressed in analemasma.

The Sun below the horizon is highly deflected when it is near the horizon, which makes it possible for us to observe the geometric center of the Sun at exactly the horizon when we stand on Earth and the real Sun is about below the horizon.

This will advance sunrise by about 3 4 minutes in most parts of the planet, and will also delay sunset by about 3 4 minutes. The effects of these two causes reach about 7 minutes. For example:

The spring equinox in Guangzhou is 6:31 sunrise, and the sunset is 18:38, and the autumn equinox is 6:

Sunrise on the 16th, sunset at 18:23.

The time to see the sunset is different in different seasons.

The sunset time is about 5 o'clock in winter and spring, and it is shorter in winter.

In the summer, the sunset time is around 6 o'clock.

Watch the sunset approximately:

More than 5 o'clock.

In general, the sunset time is between 17:30 and 19:00, depending on the local latitude and longitude.

It depends on the seasonal climate. Sunset refers to the sun's descent to the western horizon.

The latitude and longitude and seasons of each region are different, and the time of sunset will be different.

What time is the sunset

Sunset is unitary time, which refers to the period between 5 p.m. and 7 p.m., and the hour is the traditional Chinese unit of time, and one hour is about two hours today.

In ancient China, there was no such elaborate unit of timekeeping as the current "24-hour system", and the day was usually divided into 12 segments, each of which was called an hour in the order of the earthly branches.

In ancient times, people described time in a more intuitive way, usually with reference to obvious celestial phenomena and animal biological clocks. Wait.
