Chabad.org Updates Omer App

Perhaps one of the most difficult mitzvahs to fulfill properly is the counting of the Omer, which requires that each sequential day be counted (after nightfall) without missing a day—from the second night of Passover all the way until the eve of Shavuot. In addition to remembering to count on each of 49 consecutive nights, the counter needs to verbalize that night’s count and the corresponding Kabbalistic formula—all that before daybreak, or at least, before sunset the following evening.
