The word month has its origin in the Latin word mensis and allows you to refer to each specific period of the 12 intervals into which a year is divided. According to Gregorian calendar, the year is divided into twelve months. The first is January (composed of 31 days). They follow him 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 concrete examples of use: “If all goes well, we will move in the month of September”, “There are three months until the start of the tournament”, “In October it will be three months since the death of the artist”.
The name corresponding to each month is associated with Names of Latin origin (as June for Juno or July for Julius Caesar), although there are months baptized according to numbers (Thus, for example, September is inspired by the 7th or seventh; October by the idea of the eighth; November derives from 9 and December comes from the tenth or tenth). It should be noted that this enumeration ends at ten because, until the Julian reform, the calendar only consisted of ten months.
When speaking of the month, on the other hand, group of consecutive days that begins with a designated one and continues until another of the same date in the following month: “As of November 16, you who have two months to present the documentation”, “The fishing ban started yesterday and will last for three months”.
For the astronomyInstead, month is a temporal unit or magnitude that measures time from an astronomical perspective. Since observations depend on latitude, atmospheric conditions, and other factors, it is impossible to accurately anticipate how long the months will last for these types of measurements.
The Hebrew calendar
The order of days it is not the same for all the inhabitants of the earthMany 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 a year lasts is the same that it takes for the Earth to revolve around the Sun and a month, the time it takes for the Moon to circle the Earth. That is why it is said that it is a lunisolar calendar.
Originally, the sum of days that corresponded to a month was not very exact, but over the years this almanac was improved.
Currently, the one concluded by Hillel II, a wise man who existed in the 350s, is used; This calendar is the one that sets the jewish holidays through a complex algorithm, by which the exact dates of the new moon can be predicted and with them the different seasons of the year.
Although this calendar has no relationship with 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 the 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 corresponds to 2012 according to the calendar Gregorian 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 find out which Hebrew year a Gregorian corresponds to is by adding the figure 3760 to it. Ex: 2012 + 3760 = 5772.
