People in ancient times learned to measure time.Day is considered by the alternation of night and day, month - on transition in the various phases of the moon, years - on transitions of seasons.Now we all probably already know from childhood, how many days of the year.This information is easy to remember.But the question of how many weeks a year, is given very rarely.However, this knowledge will also be out of place, especially in the calculation of the number of training hours, payroll, etc.It should immediately be noted that this question should be considered only preliminary thinking about what the calendar will be discussed.
Islamic calendar
Did you know that in eastern countries often used the Islamic calendar.But he differs from that we have.In it 354 days.Recent calculated from the time when the sun goes down, not at midnight.So, how many weeks in a year is determined in the East?There they are, there are fifty (whole).Also depending on the year number in it lunar day than whole 50 weeks, more determined 3-5 days.
Jewish calendar
He officially accepted in Israel.It is used for official documents identify specific anniversaries.All months in it originate in the new moon.So, in this calendar year to a regular account for fifty full week + 3-5 days (as in Islam), but in a leap year - fifty-four weeks plus 5-7 days.
Gregorian calendar
In Russia, as in almost all European countries use the Gregorian calendar.How many weeks of the year with us?The answer is simple: fifty two - fifty-three.Of course, the number depends on whether or not a leap year and day of the week, which fell on January 1.On average, you can even bring this figure - 52.143 weeks in a year.Interestingly, for the accounting of securities, according to the European system of calculation, the new period always begins with the first week, maybe 52 minutes or 53 minutes.This happens when the 1st week of the year is less than four days.
Normal (non-leap) year includes fifty-two weeks and one day.Due to the presence of the latter in each subsequent year, days of the week (Monday, Tuesday, Wednesday, etc.) are shifted by one day compared to the previous one.After the leap this shift takes place on two days.
number of weeks in the school year
Such consensus is not observed, when the question of how many weeks in the school year.The fact that the very institution of education can vary the amount of vacation time and training.For the duration of one junior classes for seniors - the other, for students - third.Regulated by the number of weeks of study of a particular Charter school.As a rule, first-graders learn to 32-33 weeks of the year, the remaining classes of the school - from 34 to 36, and in higher education is the long duration of the school year may be 45 weeks.Learn exactly how many weeks a year of training you have to deal with, you, reading the Charter of school, college or university.Basically, this document is generally worth exploring.
Yes, however, is not so important how many weeks a year will need to learn.It is well known truth that we constantly acquire knowledge.The main thing that they were serious, deep, and brought us a favor.
