Understanding the Significance of Nisan in the Hebrew Calendar

Nisan (also known as Aviv or Cheshvan) is the first month of the Hebrew calendar. It usually falls in late March and early April in the Gregorian calendar, although the exact date varies due to the lunisolar nature of the Hebrew calendar.
Nisan is a significant month in the Jewish faith, as it marks the beginning of the spring season and the start of the agricultural cycle. It is also the month in which the Passover holiday takes place, which commemorates the Israelites' liberation from slavery in Egypt.
In addition to its religious significance, Nisan has historical importance as well. It was during this month that the Babylonian Empire conquered Jerusalem and destroyed the Temple in 586 BCE, and it was also the month in which the modern State of Israel was declared in 1948.
