The twelfth Hebrew month (counting from Nisan) is called Adar. It is the last month of the Hebrew year. Adar usually falls during the months of February/March on the Gregorian calendar. The month usually has 29 days, normally, but it has 30 days during “leap years” that is, when an additional month is added to the Jewish calendar. This additional “leap year” month is called Adar Sheni (Second Adar or Adar II).
All of this can be confusing. The Jewish calendar is a lunar calendar but in order to correlate with the sun an extra month has to be added occasionally. These calculations are fixed and reflected on the calendar just the same as the Gregorian calendar adds “leap years” where an extra day is added to the month of February. Just consult a Jewish calendar to see when there is going to be a leap year instead of trying to figure out the calculations.
The festive holiday of Purim occurs on the 14th day of the last month of the year, either Adar or Adar II. Purim is a time for celebrating the deliverance of the Jewish people during the time of Queen Esther. Read the book of Esther to understand all about Purim. Adar occurs one month before Passover when a deliverance (exodus from Egypt) also took place for the nation of Israel.
Purim and Passover are intrinsically tied together, prophetically, in ways that most do not recognize. Instead of going into all of that in this article, I would just ask that you refer to the link below about Purim to see what has been missed (by many).
Purim is not an Appointed Time of the Most High, however, like Hanukkah it does call to remembrance times of deliverance for the Jewish people and pictures future deliverance of the people of God by His Messiah Yeshua.
