In the Hebrew calendar the Day of Atonement begins at nightfall starting the tenth day of the Hebrew month of Tishri (which falls in September/October), and continues until the next nightfall. It is always observed as a one day holiday, both inside and outside the boundaries of the land of Israel, in contrast with many other Jewish holidays, which are observed for two days in the Diaspora.
Jewish groups typically teach, "The Day of Atonement absolves from sins against God, but not from sins against a fellow man unless the pardon of the offended person be secured" (Mishnah tractate Yoma 8:9). Hence the custom of terminating on the eve of the fastday (or in the 10-day period between Rosh Hashanah and Yom Kippur) all feuds and disputes. Even the souls of the dead are included in the community of those pardoned on the Day of Atonement. It is customary for children to have public mention made in the synagogue of their departed parents, and to make charitable gifts on behalf of their souls."Christians that observe the Day of Atonement normally teach that on that day they are to be at one with God. And that fasting humbles them and makes them realize how dependent they are on God for all their needs.
Lord Forgive us for our sins and guide us on our journey -let us walk before you and be blameless
