Everything in Judaism is perfect, and we see it in our calendar too.
The Jewish calendar is actually based on the moon. The Torah instructs us to count months and set the holidays based upon it: Passover on the 15th of Nissan, Yom Kippur on the “tenth of the seventh month”—and that all depends on the moon.
At the same time, G-d instructs us to celebrate Passover specifically in the month of “spring”—it must be in the springtime. And that’s where the problem starts: If the Jewish calendar is solely based on the moon, then every Jewish year slides back 11 days. Passover would be earlier every year, with Passover falling on the 20th of April this year, on the 9th of April next year, the year after that towards the end of March, and the following year in the middle of March, and so on. At that rate, we’d end up celebrating Passover in the thick of winter—and then it would get even earlier in the year! Thus, to ensure that Passover always falls in the springtime, there’s the concept of the leap year: Every two or three years, when Passover would otherwise fall too early, we push the holiday up a month by adding a second month of Adar.
That’s the reason we celebrated Passover at the end of April last year—since the year was a leap year, we added a whole month and thus ensured that Passover would fall in spring, not winter. In other words, the Jewish calendar equates the moon and the sun. It may be a calendar based on the moon, but it adjusts itself to the sun too.
WHO RUNS THE SCHEDULE?
Now, why is this of such importance to the Jewish People to the point that reckoning the Jewish calendar is the first mitzvah given to the Jewish People?
The sun and the moon symbolize the relationships between G-d and the Jewish Nation. The sun represents G-d and the moon represents the Jews. Now, the moon’s source of light is the sun itself—the moon itself has no light source and its entire existence is the fact that it is a reflector of the sun. That’s why we need to listen and get in line with G-d — so that we can collect the light of the “sun.”
And that’s why we address G-d in the masculine form.
Just as bringing a child into the world requires a male and a female, with the male being the giver and the female being the receiver, so too in our relationship with G-d, G-d is the male. He is the sun, the giver, the transmitter, the male, while we, the “Congregation of Israel,” are the moon, the taker, the receiver, the female.
That’s why we are collectively referred to in the feminine form—including the men. And that’s why the Jewish Nation is called “G-d’s Wife”, upon which the entire Song of Songs is based.
And since G-d chose us as His “wife” at the Exodus from Egypt, the first thing He gave us was the daily schedule.
Every man knows that in the house, the wife runs the calendar—she tells him where they’re going out at night, what time they’re leaving and when they’re coming back. It’s all up to her.
In like manner, G-d gave the Jewish People the Mitzvah of determining Rosh Chodesh; “You decide when we’ll meet, you decide when Passover and Yom Kippur will fall—you’re the decision-makers.” Every holiday is an encounter between the Jewish Nation and G-d, with the “wife” the one controlling the social calendar.
As the Midrash tells us: “The Ministering Angels convene around G-d and say before Him: ‘Master of the Universe! When is Rosh Hashanah?’ And He says, ‘You ask Me?! Let’s you and I ask the Earthly Court.’”
THIS IS YOUR MARRIAGE TOO
The sun and moon don’t just symbolize the relationship between the Jewish Nation and G-d, but also the relationship between husband and wife.
The husband is the sun, the transmitter, while the wife is the moon, the receiver. There’s an intrinsic difference that must be recognized so that we can successfully work together.
You have to admit that men and women are different. For example, a mom with a high fever will still get up in the morning, dress the kids, feed them, send them off to school and then go back to bed.
The guy, on the other hand—if he gets a drop of temperature above normal, let’s say 100 or 101, he immediately informs everyone not to touch him, he feels like he’s about to die, and calls into work right away that he won’t be in for a week. For him, the entire universe has ground to a halt.
Another example is shopping. When a guy goes shopping for shoes, he prays in his heart that the first pair he tries on will be the right one so he can pay right away and get out of there.
The wife, on the other hand, will sit in the store for hours measuring every shoe there is. Then, when she gets home, she measures some more, only to decide that she’s going back to the store to return the shoes because they weren’t the right ones in the first place.
Two different universes: The husband doesn’t remember what he ate yesterday, while the wife remembers the bad food they served at a wedding 20 years ago.
Now, marriage is like the calendar—built around the moon and only occasionally brought into line with the sun. So too in family life—the home is based on the woman, the anchor of the home and the manager of its spirit. Occasionally the sun and the moon must align!
