Нисан айы: еврей календарының бірінші айы

1st month of the Hebrew calendar
the Hebrew calendar

Nisan (or Nissan; נִיסָן from itiNissānu) in the Babylonian and Hebrew calendars is the month of the barley ripening and first month of spring. The name of the month is an Akkadian language borrowing, although it ultimately originates in Sumerian nisag "first fruits". In the Hebrew calendar it is the first month of the ecclesiastical year, called the "first of the months of the year" (Exodus 12:1 2), "first month" (Ex 12:14), and the month of Aviv (Ex 13:4) בְּחֹ֖דֶשׁ הָאָבִֽיב ḥōḏeš hāʾāḇîḇ). It is called Nissān in the Book of Esther. It is a month of 30 days. In the year 2024, 1 Nisan will occur on 9 April. Counting from 1 Tishrei, the civil new year, it would be the seventh month (eighth, in leap year), but in contemporary Jewish culture, both months are viewed as the first and seventh simultaneously, and are referred to as one or the other depending on the specific religious aspects being discussed.

The biblical Hebrew months were given enumerations instead of names. The new moon of Aviv, which in Hebrew means "barley ripening" and by extension "spring season"(Exodus 9:31) is one of the few called both by name and by its number, the first. Nisan and other Akkadian origin names for the equivalent lunar months in the Babylonian calendar came to be applied to the Hebrew calendar during the Babylonian captivity, in which the month of Aviv's name was Araḫ Nissānu, the "month of beginning".

Shabbat HaGadol is the sabbath which immediately precedes the 15 Nisan, the first day of Pesach, which changes due to the leap year in the Hebrew calendar.
