To be read from the eve of Shavu'ot 2021 (Sivan 5, 5781 / May 16, 2021):

Baruch atah Adonai, Eloheinu, Melekh ha'olam, asher kideshanu beh-mitzvohtav, veh-tzivanu al-sefirah ha'omer.

Blessed are you LORD, our God, King of the world (universe), who has sanctified us with His commandments, and commanded us on the counting of the Omer.

According to Rabbinic Judaism, today is the 49th day, that is, the 7th exact week of Counting the Omer (Sefirat Ha'Omer). As such, today is the brink and brim of the Omer count, that is, the penultimate to Pentecost (Hebrew: Shavu'ot).

And as today sinks into tomorrow, this day will become the 50th day, that is, 7 full (complete) weeks of Counting the Omer. And as such, tomorrow will be one step above the product of 7 days x 7 weeks of counting; this day will become the fiftieth from First-Fruits (Bikkurim), that is, the day of Pentecost (Fifty) itself.

These are the seven days and seven weeks of Counting the Omer (Sefirat Ha'Omer).

To begin the process of counting these seven days and seven weeks is the Day of First-Fruits (Yom HaBikkurim), otherwise known as the Feast of the First-Fruits (Chag HaBikkurim). On this day in biblical history, the children of Israel were instructed to bring a sheaf of their first-fruits - a bundle of barley - after they arrived and settled in the land God had previously promised and later led them to after the Exodus from Egypt. This offering to God used the first-fruits of the Promised Land to initiate the process of counting up to the 50th day, known as either the day of Shavu'ot (Weeks) in Hebrew or the day of Pentēkostḗ (Fiftieth) in Greek.
