The Jewish Calendar and Holidays (incl. Sabbath): Yom Kippur: The Holiest Day of the Year:
Is Yom Kippur the holiest day of the year?
It doesn't say in the Torah that Yom Kippur is the holiest day of the year. In fact, the Bible doesn't refer to any day as "holy" except for Rosh Ha-Shanah, which is called "holy" in Nehemiah 8:9-11. But Yom Kippur is the unique day that the Torah sets aside for atonement for our sins (Lev. 16:30,34). We can also say that
Yom Kippur was the holiest day as far as the Temple service was concerned, because only on that day was the High Priest allowed to enter the Holy of Holies.
