In a world filled with popular customs and traditions, few tend to search out the origin of how they came about. Most follow along as they have been taught following common religious practices and man-made traditions choosing to do what everyone else does because it is easy, natural and comfortable. Man-made holidays such as Christmas, Easter, New Year’s, Halloween, Valentine’s Day and other Christian holidays are kept without knowing why.  You must be willing to open your Scriptures and honestly accept what it says about the holidays of man and about the Creator's Holy Days/Feast Days.   It was on Mt. Sinai that the Creator gave Moses the dates and observances of the seven feast days.  Being that the Creator's calendar begins with a new moon, these feast days would not fall on the same dates throughout the year as man-made holidays do every year.  The only way we would know the appointed times to observe them was by looking for the sighting of the new moon in the first month and the sighting of the first fruits that come out of the ground which is barley or flax. During the time of the plague of hail the barley and flax was said to be at their full size so this would be the first sighting of the first fruits, Exodus 9:31. The basic meaning of the word Abib is the stage in the growth of grain when the seeds have reached full size.  Exodus 34:18, Leviticus 23:5 and Deuteronomy 16:1 gives the name of the first month (ABIB).  The name of the month of Abib was changed to Nisan after the Babylonian captivity (Nehemiah 2:1)  Abib/Nisan falls somewhere within the Gregorian calendar months March/April because this is the time that the first fruits began to be sighted
