Feast number 4: Feast of trumpets also called Rosh Hashanah that falls on the first day of the 7th month on God’s calendar (Leviticus 23: 23-25), this is also the season when Israel was commanded by God to blow the shofar (Hebrew trumpet), so that all may hear and exalt God as king on the earth.

Feast number 5: Yom Kippur (also called the Day of Atonement), which falls on the 10th of the 7th month (Leviticus 23:26-28), being the time when the high priest went into the holies of holy every once a year with the blood of atonement to sprinkle the ark of the covenant in the most holy place.
