Is it possible to determine exactly how many weeks per year?

People already in ancient times have learned to measure time. The day was considered by the change of night and day, the months - by the transition of the Moon in different phases, years - by the transitions of the seasons. Now all of us, probably, already from childhood know how many days in a year. This information is easy to remember. But the question of how many weeks in a year is set very seldom. However, this knowledge will also be superfluous, especially when calculating the number of teaching hours, when calculating wages, etc. It should be noted immediately that this issue should be considered only by first deciding which calendar will be discussed.

Islamic calendar

Did you know that in the eastern countries the Islamic calendar is most often used. And it differs from ours. There are 354 days in it. The latter are calculated from the moment the sun sets, not from midnight. So, how many weeks in the year is it determined in the East? There are fifty of them (whole). Also, depending on the year, the number of lunar days in it, in addition to as many as 50 weeks, another 3-5 days are determined.

The Jewish Calendar

It is officially accepted in Israel. Used for official documents, the determination of specific memorable dates. All the months in it take their origin in the new moon. So, in this calendar in an ordinary year, there are fifty full weeks + 3-5 days (as in Islamic), but in a leap year - fifty-four weeks + 5-7 days.

Gregorian calendar

In Russia, as in almost all European countries, the Gregorian calendar is applied . How many weeks a year do we have? The answer is simple: fifty-two-fifty-three. Of course, the number depends on whether a leap year or not, as well as on the day of the week on which the first of January fell. On average, you can even get such a figure - 52.143 weeks a year. Interestingly, for accounting papers, according to the European system of calculation, the new period does not always start from the first week, or maybe from the 52nd or 53rd. This happens when the first week of the year is less than four days.

A typical (non-leap) year includes fifty-two weeks and one day. Due to the presence of the last days of the week in each subsequent year (Monday, Tuesday, Wednesday, etc.) are shifted by 1 day, if compared with the previous one. After a leap, this bias occurs for two days.

Number of weeks in the school year

This unity of opinion is not observed when the question is asked about how many weeks in the school year. The fact is that the institution of education itself can vary the amount of academic and vacation time. For junior classes duration is one, for seniors - another, for university students - the third. The number of weeks of study by the Charter of a particular educational institution is regulated. As a rule, first-graders study 32-33 weeks a year, the rest of the school classes - from 34 to 36, and in higher education the longest academic year can be 45 weeks. To find out exactly how many study weeks in the year you will be engaged, you can by reading the Charter of the school, college or university. In principle, this document is generally worth exploring.

Yes, however, it is not so important, how many weeks in a year it will be necessary to study. After all, the truth is known, that we get knowledge constantly. The main thing is that they are serious, profound and beneficial to us.
