The word month It has its origin in the Latin word mensis and allows reference to each specific period of the 12 intervals into which a year is divided . According to Gregorian calendar , the year is segmented into twelve months. The first is January (composed of 31 days). They follow February (which varies between 28 or 29 days, depending on what year it is), March (31 days), April (30 days), may (31 days), June (30 days), July (31 days), August (31 days), September (30 days), October (31 days), November (30 days) and December (31 days).
To cite specific examples of use: “If everything goes well, we will move in the month of September”, "There are three months to go before the tournament begins", “In October, three months will have elapsed since the artist's death”.
The denomination corresponding to each month is associated with Name (s of Latin origin (as June by Juno or July by Julius Caesar ), although there are months baptized according to numbers (Thus, for example, September is inspired by the 7th or 7th; October in the idea of 8th; November is derived from 9th and December comes from 10th or 10th). It should be noted that this enumeration concludes in ten because, until the Julian reform, the calendar was only made up of a dozen months.
When talking about the month, on the other hand, you point to group of consecutive days which begins with one indicated and that reaches another of the same date in the following month: “As of November 16, you have two months to present the documentation”, "The fishing ban began yesterday and will last for three months".
For the astronomy , instead, month is a unit or temporal magnitude that measures time under an astronomical perspective. Since the observations depend on latitude, atmospheric conditions and other factors, it is impossible to accurately anticipate how long the months will last in this type of measurement.
The Hebrew calendar
The order of days it is not the same for all the inhabitants of the earth , many of them are governed by old traditions or religions and frame their existence around a particular calendar.
The Jews , for example, are governed by the Hebrew calendar, whose cycle responds to the location of the Earth with respect to the Sun. Thus, the time that lasts a year is the same that it takes the Earth to revolve around the Sun and one month, which takes the moon to circle the Earth. That is why it is said that it is a lunisolar calendar.
In the beginning, the sum of days that corresponded to a month was not very accurate, but over the years said almanac was improved.
Currently, the one concluded by Hilel II is used, a sage that existed in the 350s; said calendar is the one that sets the Jewish holidays through a complex algorithm, by which you can predict the exact dates of the new moon and with them the different seasons of the year.
Although this calendar has no relation to Chinese and Arabic (calendar used before the establishment of the Islam in these lands), certain aspects of both coincide; However, all of them clearly differ from Gregorian, explained above.
The beginning of the Hebrew calendar took place, according to Jewish tradition, on October 7, 3761 BC. C. (Sunday); this means that that day was day 1 of month 1 of year 1. Therefore, the year in which we live corresponding to 2012 according to the calendar Gregorian It is equivalent to 5773 of the Hebrew calendar. The 5773 began on September 16, 2012 and will end on September 4, 2013. The way in which you can know which Hebrew year corresponds a Gregorian is adding the figure 3760 to it. Ex: 2012 + 3760 = 5772.
