Islamic calendar
Did you know that in the eastern countries most oftenThe Islamic calendar is used. And it differs from ours. There are 354 days in it. The latter are calculated from the moment when the sun sets, and 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, determining 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 Europeancountries, apply the Gregorian calendar. How many weeks a year do we have? The answer is simple: fifty-two-fifty-three. Of course, the number depends on whether the leap year is or not, and also 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 securities, 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.
The usual (non-leap year) includesfifty 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
There is no such unity of opinion whenThe question is 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 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 are engaged in, 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.
