7 weeks from the second night of Pesach to the day before Shavuot ㊾

Days of the Omer for Hebrew Year 4600 began on Tuesday, 27 March 0840 and ended on Tuesday, 15 May 0840.

Counting of the Omer (or Sefirat Ha’omer, Hebrew: ספירת העומר) is a verbal counting of each of the forty-nine days between the Jewish holidays of Passover and Shavuot. This mitzvah derives from the Torah commandment to count forty-nine days beginning from the day on which the Omer, a sacrifice containing an omer-measure of barley, was offered in the Temple in Jerusalem, up until the day before an offering of wheat was brought to the Temple on Shavuot. The Counting of the Omer begins on the second day of Passover (the 16th of Nisan) for Rabbinic Jews, and after the weekly Shabbat during Passover for Karaite Jews, and ends the day before the holiday of Shavuot, the ‘fiftieth day.’.
