To find out how many seconds per year, you need eithera lot to add and multiply, or just multiply a lot. In the first case, you need to look at each time of the year and calculate how many time meters there are, then add all the obtained indicators to an integer (which we are actually looking for), in the second - apply the knowledge obtained in kindergarten and multiply on the right figures. In order to more fully reveal the topic, we will select the first item, that is, consider how many in a year, minutes and seconds not just in general, but in each season separately (winter, spring, summer and autumn). This way is more long and boring, so those who wish can immediately flip through the article to the end, which provides a simpler way to find out the information of interest.
In addition to the number of seconds, it would be superfluous to mentionabout how many minutes a year, since it is not less important - just like days. And anyway, information about how much time in a year is useful and can be useful to everyone. Yes, remembering complex six- and eight-digit numbers can be difficult, but the number of months, days, hours and days in each other is quite possible to remember.
So, for starters, some background information:
That's all, in fact, thanks to this information you can already find out how many seconds in a year. But let's start the "analysis of flights".
March. The first spring month contains:
April
May
Addition: 2 678 400 + 2 592 000 + 2 678 400.
The result in seconds: 7,948,800.
June. Summer comes, the first month of which contains:
July
August
September. Carries this month in itself:
October
November
Addition: 2 592 000 + 2 678 400 + 2 592 000.
The result in seconds: 7,862,400.
A leap year is an event that occursevery four years at the end of winter. 11 months pass the same way as always, but not February. He is deprived of days (unlike his "comrades," he does not have 30 or 31 days, but only 28), and with the help of a leap year he can feel a little closer to his "relatives", because it was during this period of days in February 29. It does not much exceed the usual amount, moreover, it still does not reach the other months, but in the least this last winter month nevertheless approaches the coveted figure of 30. True, it can not grow up to it ever.
Well, when we sorted out the leap years, we can start the usual calculation.
December. Winter comes and last month before next year. It carries in itself:
January
Low Monthly February:
Addition: 2 678 400 + 2 678 400 + 2 419 200.
The result in seconds: 7,776,000.
Leap Year February:
Addition: 2 678 400 + 2 678 400 + 2 505 600.
The result in seconds: 7,862,400.
So we counted all the weeks, days, hours, minutes. Now you can give a specific answer to the question about how many seconds in a year.
In the non-leap year:
In a leap year:
That's all. How did we find out how many seconds of the year? In fact, everything is very simple. Officially, we counted the number of spring, summer, autumn and winter seconds, and then put them together. However, there is the same easy and simple method that was mentioned at the beginning of the article: 365 days x 24 hours x 60 minutes x 60 seconds. In the case of a leap year, change 365 to 366 and do the same, ie multiply the day by the hour, minutes and seconds. As a result, the same results as above are obtained. With a calculator, this method does not allow you to memorize large numbers, but simply and quickly counts the seconds when a particular situation requires it. However, those who have a good memory, can remember all the necessary numbers.
