How many days and hours in 1 year. How many hours a year

Have you ever thought about how many hours we live on a long annual interval between January 1 and December 31? To be accurate, to name a specific number of hours, minutes and seconds for all the upcoming or past years is impossible. First, there are leap years, and secondly, on the territory Russian Federation Until 2011 it was customary to change the time for this season. If we talk about rounded numbers, use the following formula: a product of the number of days and hours in one day.

Thus, even with the most common calculator, you can withdraw a number 8760 . (365 days multiplied by 24 hours). If the year leap, I multiply 366 days for 24 hours, and get 8784 watches a year.

At the same time, the modern population also interests the number of hours a year for which you can make money. To calculate this number, take away from 24 hours the amount of your sleep and rest, after which multiply the value obtained on 365. Suppose you sleep 8 hours a day. We add an hour by this time to the morning procedures and fees, time on the road, etc. in the end, it turns out somewhere 2 hours.

8 + 2 \u003d 10 hours you need for sleep and other cases.

24-10 \u003d 14 hours you can devote to work.

14 Multiply with 365, we get 5110 hours a year.

If the year leap, then multiply 14 hours by 366, and we get 5124 hours.

Note: When calculating the clocks that can be spent on earnings, take into account weekends, hospital, as well as various holidays.

Some more statistics

With the number of hours (including those that can be devoted to work) in the year we decided. Now consider others interesting Factswhich boasts a year boast.

1. Every year - 12 months and 365 (366) days.
2. In each individual, there may be a different number of weeks. It depends on what day of the week the current year began and he has begun. For the averaged data, it is possible to use such a formula: 365 days divided for 7 days, we get 52.1 weeks. In the leap year, the inhabitants of the planet live more than 52 weeks (366 days divided for 7 days, we get 52.2 weeks).
3. How many seconds in the year? Now check. 60 seconds (minute) multiply by 60 minutes in an hour, multiply by 24 hours in days, and multiply by 365 days a year, we get 31,536,000 seconds a year. The leap year is obtained 31,622,400 seconds.

Here is such an entertaining mathematics that gave you new knowledge about our world.

Hour - This is a unit of measure of time equal to 60 minutes, 3600 seconds or 1/24 days. Abbreviated Russian designation: h, international: h. The word "hour" happened from the verb "Caiaty", which means "waiting."

Year - Conditional time measurement unit, equal to 365 days (day) or 366 (leap year, which is divided into 4). This is the period of circulation of the Earth around the Sun. Abbreviated Russian designation: G., in english language - y or yr.

The year consists of four times: winter, spring, summer, autumn and 12 months. The word "year" occurred from the Old Slavonic "Year" and means "Time, Year" or "Gooditi" - "please, satisfy". There are such concepts as millennium - 1000 years old, a century is 100 years old, a decade - 10 years, half of the year - 6 months, a quarter - 3 months.

In one year - 8760 hours, in one hour - 1/8760.

How to translate years in hours

To translate years during hours, you need to multiply the number of years to 8760.

Number of hours \u003d number of years * 8760

For example, in order to find out how many hours in 2.5 years, you need 2.5 * 8760 \u003d 21900 hours.

How to translate the clock during the years

To translate the clock during the years, it is necessary to divide the number of hours by 8760.

Number of years \u003d number of hours / 8760

For example, in order to find out how many years in 4380 hours, you need 4380/8760 \u003d 0.5 years (half a year).

Arithmetic calculations necessary to determine the number of hours folded per year are not distinguished by complexity.

Calculation of the number of hours

Quantitative relations of time measurement units to someone may not seem quite comfortable, as they are not painted ten. It is explained by the fact that civilization inherited them from ancient Babylon, where there was not a decimal number system, the usual modern man, and twelve, therefore, the ratio of time units are multiple 12. It is not an exception and number of hours - 24.

To get the number of hours a year, you just need to multiply 24 by the number of days that make up the year. In the Grigorian calendar, according to which lives modern civilization, alternate innocent years and leaps. In the first case, the year contains 365 days, and in the second - 366. The multiplication of these number by 24 gives 8760 and 8784, respectively.

So, in the leap year 8784 hours, and in a non-obvious - 8760. If anyone has a desire to celebrate a 10,000 hour anniversary of any event, you need to count on his date one year and add 51 days, if the year is neviscable, or 50 days if leap. To clarify, it would be necessary to add a few more hours, but it is unlikely that someone will strive for absolute accuracy.

Year from the point of view of astronomy

The duration of the year installed on the calendar is to a certain extent conditional. Man conveniently started new Year Together with new days. In reality, the period of circulation of the Earth around the Sun, which is considered a year, does not coincide with earthly days.

From the point of view of the observer, which is on earth, the beginning and completion of the turnover of the Earth around the Sun corresponds to the day of the Spring Equinox. Astronomers call this period at the tropical year. During this time, the longitude on which the sun can be observed is increased by 360 degrees, passing a complete circle.

The tropical year, which take into account the astronomers, is somewhat longer calendar. That is why the calendar had to introduce leap years. Its duration is 365 days for 5 o'clock 48 minutes and 46 seconds. Consequently, the previously obtained 8784 hours must be added another 5 hours and almost 49 minutes. In this case, the duration of the astronomical year turns out to be approximately 8789 o'clock 49
