The term 'Post-Passover Period' refers to the seven-week period of time that follows the Jewish holiday of Passover. The Hebrew word for this period is 'Omer, ' which is a four-letter word. This period is marked by counting the days and weeks from the second day of Passover until the holiday of Shavuot. During this time, Jews are encouraged to reflect on the spiritual significance of the Exodus from Egypt and to focus on personal growth.
