While the Torah tends to designate specific calendar dates for the Chagim, Shavuos is a notable exception. Shavuos was the harvest festival, but it also marks the anniversary of Sinai when the Torah was given to humanity. Yet the way the Torah conceives of it, it’s not about a specific calendar date; it’s all about the countdown:
וּסְפַרְתֶּם לָכֶם מִמָּחֳרַת הַשַּׁבָּת מִיּוֹם הֲבִיאֲכֶם אֶת־עֹמֶר הַתְּנוּפָה שֶׁבַע שַׁבָּתוֹת תְּמִימֹת תִּהְיֶינָה. עַד מִמָּחֳרַת הַשַּׁבָּת הַשְּׁבִיעִת תִּסְפְּרוּ חֲמִשִּׁים יוֹם וְהִקְרַבְתֶּם מִנְחָה חֲדָשָׁה לַה – And from the day on which you bring the sheaf of elevation offering—the day after Shabbos—you shall count seven weeks. They must be complete: you must count until the day after the seventh week—fifty days; then you shall bring an offering of new grain to Hashem. (23:15, 16)
This count from Pesach to Shavuos is the mitzvah we know as Sefiras HaOmer. As the Sefer HaChinuch notes, standing at Sinai, there was an excellent reason to count the days to Shavuos; Moshe was gone, and they were supposed to wait for him to come back, and when they finished counting, they experienced Divine revelation. But when we finish the countdown, nothing ever happens. Shavuos is just an anniversary!
Our ancestors counted a Sefira to Shavuos so they could receive the Torah. Why do we count our Sefira to Shavuos, where nothing happens?
R’ Yitzchok Berkovits observes that it is precisely correct to observe that nothing happens on the anniversary of receiving the Torah; because Torah isn’t something that happens to humans – that was the one-time event. Since then, it’s something humans have to work for, and that’s why we count Sefira.
A birthday is just an anniversary, and an anniversary is just an anniversary. If you just wake up on the morning of your kid’s birthday, nothing at all will happen. But what can make a birthday or anniversary incredibly special is if you put heart and thought into the days leading up to it. Did you order a cake, balloons, presents, and write cards? Plan a party, invite their friends, remind loved ones, book a table at their favorite restaurant, order their favorite treats? If you did some of those things, then instead of nothing happening, something extraordinary will happen; just another Tuesday will magically transform into a timeless feeling of deep love and happiness that will linger for a lifetime.
It might not be right to say that revelation at Sinai was the main event, and then the anniversary is just an anniversary. As the Kli Yakar notes, the Torah only ever refers to Shavuos by its agricultural component, and never for the commemorative anniversary aspect of Sinai; because the date that humans receive the Torah is specifically not located in the past – it’s forever in the here and now. Quite arguably, it’s more correct to say that Sinai was a thing that happened, but it’s what we do with it now that is the main event.
So sure, Shavuos is just an anniversary; but Sefira is the effort we invest in the lead-up. If we think that Torah is something that just happens to us with no investment of effort or desire, we have fundamentally missed the nature of what the Torah asks of us. We have to search for it, desire it, and labor for it to become a part of us. It does not happen by kicking back to listen to a nice class or reading a good book.
If we believe that the Torah is ultimate wisdom, the handbook for making humans more human, the guide to living a good life, how badly do we want it? How lost are we without it? We know all too well how blind and stupid we can be, hurting ourselves and each other needlessly over the silliest nonsense. The Torah asks everything of us, yet returns everything richer and fuller. If we take it seriously, we can curb our worst excesses, draw out our finest qualities, honing and refining our character and personalities into the brightest fires that warm and light the lives of everyone we touch. But it’s not the calendar date that anchors and orients us; because nothing happens; it’s just Tuesday! It’s our countdown that makes all the difference.
The sad reality is that even the best of us believe that just learning Torah improves our character by osmosis, but most of us know from lived experience that it doesn’t; you actually have to put in the effort.
