Here is your short paragraph on Yom Kippur:
This is the holiest day in the Jewish calendar that occurs in the month of September or October, observed on the tenth day of the seventh month in the Hebrew calendar.
After kindling the Yom Kippur lights at home on the eve of the day, the family, generally dressed fully in white, go to the synagogue for the Kolnidree (all vows) service.
This is a solemn declaration absolving all members of the faith from the unfulfilled vows unwittingly or impulsively made between God and man.
The Day of Atonement is ordained by the Torah as a day for ‘affliction of souls’ and atonement of sins. A rigorous fast is observed from sunset to night fall of the next day.
