People already in antiquity learned to measure time. Days were counted according to the change of night and day, months - according to the transition of the Moon into different phases, years - according to the transitions of the seasons.
Now we all probably know from childhood how many days there are in a year. This information is easy to remember. But the question of how many weeks in a year is extremely rarely asked. However, this knowledge will also be useful, especially when calculating the number of study hours, when calculating salaries, etc. It should be noted right away that this question should only be considered after deciding which calendar will be discussed.
Islamic calendar
Did you know that in Eastern countries the Islamic calendar is most often used. And it differs from ours. It has 354 days. The latter are calculated from the moment the sun sets, not from midnight. So, how many weeks in a year is determined in the East? There are fifty (whole) of them. Also, depending on the year, the number of lunar days in it, in addition to as many as 50 weeks, another 3-5 are determineddays.
Jewish calendar
He is officially accepted in Israel. Used for official documents, determining specific memorable dates. All months in it originate on the new moon. So, in this calendar, in a normal year, there are full fifty weeks + 3-5 days (as in the 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 used. How many weeks in a year do we have? The answer is simple: fifty-two - fifty-three. Of course, this number depends on whether it is 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 deduce 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, but maybe from the 52nd or 53rd. This happens when there are fewer than four days in the 1st week of the year.
A normal (non-leap) year has fifty-two weeks and one day. Due to the presence of the latter, in each subsequent year, the days of the week (Monday, Tuesday, Wednesday, etc.) are shifted by 1 day when compared with the previous one. After a leap year, such a shift occurs for two days.
Number of weeks in the school year
There is no such unity of opinion when it comes to the question of how many weeks are in the school year. The fact is that the educational institution itself can vary the number of educational andvacation time. For junior classes, the duration is one, for seniors - another, for university students - a third. The number of weeks of study is regulated by the Charter of a particular educational institution. As a rule, first-graders study 32-33 weeks a year, the rest of the school - from 34 to 36, and in higher education the longest academic year can be 45 weeks. You can find out exactly how many academic weeks a year you have to study by reading the Charter of the school, college or university. In principle, this document is generally worth studying.
Yes, however, it is not so important how many weeks a year you will need to study. After all, the truth is known that we receive knowledge constantly. The main thing is that they be serious, deep and benefit us.
