The Omer is counted every evening after nightfall, from the second night of Passover till the night before Shavuot
Forgot to count the Omer at night? Count the following day, but without a blessing. On subsequent nights, continue counting with a blessing as usual.The blessing is made only if every day has been counted; if you missed a day, say the day’s count without the blessing.
