How many hours, minutes, and seconds are there 365 days a year?

The exact time of year is 365 and 1 4 days. That's why there are leap years, which become 29 days in February every four years.

Measurement of the Year》 There are many ways to calculate the time of a year in China, but I know of five types: Lunar year: Seen in the Ancient Six Calendars, it is the time required for 12 synodic months (i.e., 12 full moons), about the day.

Year of return: Because the ancients could not leave the earth and observe the time it takes for the earth to make one revolution in space, they used an indirect method to measure the daily movement of the sun immediately, and the shadow of the sun must be the same length when the sun is in the center of the spring and autumn equinoxes, and we can use the time required for the sun to pass through the vernal equinox twice in succession to determine the year, which is 365 days, 5 hours, 48 minutes and seconds, but because the earth's axis of rotation oscillates (the so-called precession), the spring equinox will be about 20 minutes earlier than the previous year. Therefore, it is not really the time for the Earth to make one revolution. Seen in the Ancient Six Calendars sidereal year:

Seen in the "Great Ming Calendar", the time for the real earth to revolve around is 365 days, 6 hours, 9 minutes and seconds. Perigee year: The time when the earth passed perihelion twice, because ancient China did not go into space to see the earth's revolution, it was not used, and the perturbation of the planets to the earth is also calculated, which is 365 days, 6 hours, 13 minutes and seconds.

Eclipse Year: Seen in the Three Unified Calendar, it is the time when the Moon passes through the ascending node twice, which is the day. "The Year of a Foreign Country" However, the first time to determine the length of a year was not China, in ancient Egypt, people used the brightest star of the day, Sirius, to determine the distance between the two rises on the horizon to determine a year of 365 days, this method is actually the Chinese return year, when Sirius rises, it is the beginning of winter, the period of the Nile flooding.

Both Egypt and China use the 365-day Earth year as the length of a year, but in the Mayans, they use the distance between the two times Venus rises above the horizon to measure a year as 686 days, you may ask, how is that different from Sirius dating, because Venus is a planet and will orbit, but Sirius does not, so the Mayan agricultural period also needs to be appropriately adjusted. In this respect, China is indeed superior to the Maya.

8,760 hours, 525,600 minutes, 31,536,000 seconds.

Analysis: 1 day, 24 hours, 365x24=8760 hours, minutes: 365x24x60=525600 minutes, seconds: 525600 minutes, x 60=31,536,000 seconds.

It's 36 hours, it's 50,000 minutes, it's 68 seconds.

It was 8,760 hours, 525,600 minutes, and 31,536,000 seconds.

Suddenly I felt that time was so short......

1 year = 8760 hours = 525600 minutes = 31536000 seconds.

The analysis is as follows: 1 year = 365 days.

1 day = 24 hours, i.e. 365 24 8760 hours.

1 hour = 60 minutes, i.e. 8760 60 525600 minutes.

1 minute = 60 seconds, i.e. 525600 60 31536000 seconds.

365 days is 8760 hours, 525600 minutes, 3153600 seconds.

There are 24 hours in a day, an hour has 60 minutes, and a minute has 60 seconds, then a day = 24 * 60 = 1440 minutes = 1440 * 60 = 86400 seconds.

Then 365 days = 365 * 24 = 8760 hours.

365 days = 365 * 1440 = 525600 minutes.

365 days = 365 * 86400 = 31,536,000 seconds.

There are 365 days in a year, 8760 hours, 525600 minutes, and 31,536,000 seconds in 365 days.

Day = 24 hours.

1 hour = 60 minutes.

1 minute = 60 seconds.

One year = 365 days = 8,760 hours = 525,600 minutes = 31,536,000 seconds.

Knowledge Expansion:The earth revolution around the sun is the rotation of the earth around the sun. Just as the rotation of the earth has its own unique regularity, the rotation of the earth is caused by the gravitational field of the sun as well as the action of rotation.

The rotation of the earth also has its own laws. The laws of the earth's revolution are from the earth's orbit, the earth's orbital plane, the yellow-red angle, the period of the earth's revolution, the speed of the earth's revolution and the effect of the earth's revolution.

The earth revolves around the sun in one round, which is one year. It has two cycles, one is the sidereal year, which is 6 hours, 9 minutes and 10 seconds on the 365th day, and the other is the return year formed by the direct sun's direct point moving back and forth between the north-south upward and boring return lines, that is, 5 hours 48 minutes and 46 seconds on the 365th day. What we usually call a year is usually 365 days, but according to the above, after 4 years, an extra day is added to the year.

So a common year is 365 days, and a leap year is 366 days (i.e., the number of years is divisible by 4).

365 days in a year is 365 * 24 = 8760 hours.

8760*60=525600 minutes.

525600*60=31,536,000 seconds.

8,760 hours, 525,600 minutes, 31,536,000 seconds.

Analysis: 1 day 24 hours, 365x24=8760 hours.

Minutes: 365x24x60=525,600 minutes

Seconds: 525,600 minutes x 60 = 31,536,000 seconds
