In the sixth aliyah we read some laws of the observation of Pesach beginning on the 14th of the month of Nissan and continuing for seven days of eating matzo. Then we read about the observation of Shavous, and Rosh Hashanah, with the blowing of the shofar. After that, the Torah discusses Yom Kippur, where we are to afflict our souls for a full night and day, in repentance. The oral law defines afflicting one's soul as abstaining from eating, washing, anointing, wearing leather shoes, and marital relations.
