When does the new Jewish day begin?

The counting of the days of ‘omer connects the Holiday of Pesach, the commemoration of our physical freedom, with Shabu’ot, the day we received the Tora.  Without getting out of Egypt, it would not have been possible for us to receive the Tora. And without receiving our Tora we would have taken with us Egypt’s gods, mores and values.  Only once we were free from Pharaoh we were at liberty to choose to be under God’s commandment, and accepted to become His chosen people .

The days of the Omer are counted at night. Because for us Jews, the new day starts at night.

Now, at what precise moment the new day starts, and at what time the previous day ends is a complicated technical Halakhic matter.

Very briefly: there are two possible astronomic indicators for the new day

  1. Sunset, when the sun disappears from sight
  2. Nightfall, which is marked by the visibility of the stars in the sky.

All Rabbis agree that before sunset it is still considered day # 1. And most Rabbis agree that after three medium stars are visible it is considered day #2.  Now, the time in between sunset and the appearance of the three stars is known as the twilight zone or in Hebrew, ben hashemashot. This time-period fluctuates between 15 min (13 ½ to be precise) to 30 minutes or more, depending on many variables, such as geographic location, year’s season, etc.

Regarding Shabbat, for example, we take the strictest stand by receiving Shabbat always before sunset and ending Shabbat after three medium stars are visible.

In most Sephardic communities the starting time to count the ‘omer is 15 minutes after sunset.

In exceptional circumstances Rabbis would authorize to count with Berakha earlier, but never before sunset.

The Omer offering

 

🌾 THE STORY OF THE KORBAN HA’OMER

In the times of the Bet HaMikdash, after the long winter, the fields of Israel began to turn golden—because wheat and barley started to grow. From the flour of wheat and barley you can prepare the most essential foods: bread, cookies, pastries, pasta, barley soup, and many more nutritious and delicious things.

The farmers looked at their crops and were very excited. The new grain was ready!

But there was one very important rule: 👉 No one could eat anything made from the new grain yet!

That meant: ❌ No bread ❌ No cakes or pastries ❌ No pasta ❌ No barley soup

👉 Nothing made from the new flour.

Food made from the new grain before the Omer offering was called CHADASH, and it was considered temporarily forbidden — almost like “non-Kosher.” Why? Because first, something very special had to happen in the Bet HaMikdash.

🌙 THE NIGHT HARVEST

When the first day of Yom Tob of Pesach ended, after nightfall:

People gathered in the fields near Yerushalayim. Thousands of Jews were there, watching and celebrating.

A few stalks of barley were cut by special messengers sent from the Bet HaMikdash — called Sheluche Bet Din — who were officially appointed to perform this mitzvah.

They cut the barley in a formal and very public way, while everyone watched.

They would even ask the crowd: 👉 “Has the sun set?” —and everyone answered: “Yes!” 👉 “Shall we cut?” — and everyone answered, “Yes! Cut!”

This happened three times, to make sure everyone saw and heard. It was a big celebration! 🎉

🏛️ THE NEXT DAY — IN THE BET HAMIKDASH

The next day (the second day of Pesach):

The barley was brought to the Bet HaMikdash. The Kohanim:

  • Cleaned it, removing the husks from the grain
  • Ground it into very fine flour—sifted 13 times to make it extremely pure and fine, much more than regular flour ✨
  • Prepared one special measure called an “Omer”

📏 How much is an Omer? About 2.5–3 pounds of flour—roughly the weight of a large bag of flour you might see at home!

🌾 WHAT DID THEY OFFER FOR THE KORBAN HA’OMER?

It was not just plain flour. The Korban ha’Omer was a special preparation:

👉 Fine barley flour 🌾 👉 Mixed with oil 🫒 👉 With levonah (frankincense) placed on top 🌿

Here is how it was made, step by step:

  1. The barley was ground into very fine flour
  2. It was sifted 13 times until perfectly pure
  3. The flour was mixed with oil
  4. Levonah (frankincense) was placed on top
  5. A portion was burned on the Mizbeach—the main altar of the Bet HaMikdash
  6. The rest was eaten by the Kohanim

Once that offering was made, all the wheat, barley, flour, and bread from the new harvest became completely permitted to eat! ✅

🎯 WHY WAS THIS SO IMPORTANT?

This korban was like saying: 👉 “Everything we have comes from ה׳.”

Only after we brought this offering and recognized that everything comes from HaShem: ✔ The new grain became permitted ✔ People could now eat from the new harvest (Chadash)

🏪 WHAT HAPPENED IN THE MARKETS?

As soon as the Korban ha’Omer was offered—everything changed!

The moms, the kids, the farmers, the bakers, the sellers in the market — everyone was happy and excited. They could finally sell and buy all the new goods: 👉 Fresh bread, new flour, cakes, and all products from the new harvest 🍞🎂

🔢 SEFIRAT HA’OMER — COUNTING THE OMER

From that very moment, something else began:

👉 That night — the night after the Omer was offered — the people began to count:

49 days—from the Omer → all the way to Shabuot 🎊

  • The Omer was offered during the day (2nd day of Pesach)
  • That night → the new day begins in the Jewish calendar
  • 👉 From that night, people started counting: Day 1 of the Omer

✔ We do not rush to enjoy things. ✔ First we recognize that everything comes from ה׳ ✔ Then we use it properly 🙏

 

DID YOU KNOW?

 

🌿 WHAT IS LEVONAH?

Levonah is a special white resin — like a natural gum or sap — that comes from a tree called the Boswellia tree.

Here is how it works:

When you make a small cut in the bark of that tree, a thick white liquid slowly drips out — almost like when you cut a fruit and juice comes out. That liquid dries and hardens into small white crystals.

When you burn those crystals, they produce a beautiful, sweet, and very strong smell — like a perfume from nature. 🌸

Why was it used in the Bet HaMikdash?

The Kohanim placed levonah on the flour offering. When it was burned on the Mizbeach, the sweet smell rose up like a gift to ה׳ — almost like saying “this offering is precious and holy.”

In fact, the Hebrew word לְבוֹנָה / Lebonah comes from the word לָבָן / laban—which means white—because of its beautiful white color. ⬜

Did you know? 🌍

The Boswellia tree grows in special dry and rocky places — like parts of the Middle East and Africa. Levonah was considered very precious and valuable in ancient times, almost like gold. Kings and traders would travel long distances to buy it!

Today we call it by its English name: frankincense.

What is Lag laOmer?

16th of Iyar, 5770 (31 days of Omer. 4 weeks, 3 days)

33 of Omer

Lag BaOmer (for Sephardic Jews is more accurate to say: “Lag laOmer”) means the 33rd day of the count of the Omer. The restrictions of mourning are lifted on this day and weddings, parties, etc are permitted from this day on.
This year it will fall this coming Saturday night/Sunday. During the time of Rabbi Akiba (approx. 150 of the Common Era) 24,000 of his students died from a divine-sent plague during these days of the Omer. The Talmud says that this was because they did not show proper respect to one another. The 33rd day of the Omer this plague ended. Another interpretation is that the students fell as they participated in Bar Kokhba’s revolt against the Romans (Rabbi Akiba was known for his support of bar Kokhba’s revolt).
Some of rabbi Akiva students survived, among them Rabbi Shimon bar Yochai who became one of greatest teacher of Torah in his generation and who is mostly known for authored the Sefer haZohar, “The book of splendor” the main book of Kabbalah (Jewish mysticism).

According to tradition, Rabbi Shimon Bar Yochai passed away on the 33rd day of the Omer. Lag laOmer is known among Sepharadic Jews as the Hillulah (wedding) De Rabbi Shimon bar Yochai. Very briefly: During his lifetime –which included 12 years of isolation- Rabbi Shimon achieved the highest possible level of human attachment to God. The rabbis of the Kabbala called this level metaphorically “engagement” (Irusin) which is when a Jew is totally, passionately and exclusively dedicated to God. If during his lifetime, the Rabbis of the Kabbalah explain, one has achieved this superior level, then his departed soul will be “married” (I insist: metaphorically), in other words, intimately connected to the Ziv haShekhina (the Almighty’s Splendorous Presence).
