The shalosh regalim are the crown jewels of the Jewish year. Pesach commemorates the Exodus, Shavuot celebrates the giving of the Torah, and Sukkot is the festival that memorializes Hashem’s unlimited chesed to our people who dwelt in sukkot following the Exodus.
There is a singular difference that obtains, however, between Pesach and Sukkot, and Shavuot: The Torah associates the first two with specific calendrical dates, whereas Shavuot has none:
“In the first month [Nissan], on the fourteenth of the month, in the afternoon, [you shall sacrifice] the Passover offering to the L-rd. And on the fifteenth day of that month is the Festival of Unleavened Cakes to the L-rd; you shall eat unleavened cakes for a seven-day period (Vayikra 23:5-6). Speak to the children of Israel, saying: On the fifteenth day of this seventh month [Tishrei], is the Festival of Sukkot, a seven-day period to the L-rd. (Vayikra: 23:34). You shall count seven weeks for yourself; from [the time] the sickle is first put to the standing crop, you shall begin to count seven weeks. And you shall perform chag Shavuot (the Festival of Weeks) to the L-rd, your G-d, the donation you can afford to give, according to how the L-rd, your G-d, shall bless you (Devarim 16:9-10).”
How can we understand this fundamental difference between Shavuot and the other chagim? I believe we can find our answer by borrowing a concept from the discipline of Physics. Since the time of Albert Einstein, modern physics has maintained that there are four dimensions: length, depth, height and time. Pesach and Sukkot are squarely anchored in each of these dimensions, since they deal with different aspects of our people’s physical salvation (hatzalat gufani) in the face of what appeared to be impossible odds. Moreover, the redemption that unfolded during these days was brought about through objects of nature, such as blood, frogs, lice and wild animals etc. (the Ten Plagues), and the sukkot themselves.
The chagim of Pesach and Sukkot, therefore, were given their calendrical dates, i.e. clearly designated times, to indicate that the entire process of redemption took place within the physical universe, and within Physics’ four dimensions.
Shavuot, however is inherently dissimilar to Pesach and Sukkot in one fundamental sense, namely, it represents spiritual salvation (hatzalat ruchani); for on this day our forebears encountered the Almighty on a lonely mountain in the wasteland of the Sinai Desert, accepted His holy Torah and forged an eternal relationship. As this was a purely miraculous spiritual event, it was outside of Physics’ four dimensions — including time itself.
The Torah, therefore, did not assign Shavuot a fixed date, precisely to indicate that it was beyond time, and consequently, unique. When we celebrate the festival of Shavuot, therefore, we are confirming our spiritual connection to Hakadosh Baruch Hu, His holy Torah, and the future of the Jewish people.
May this Shavuot be a joyous chag wherein we strengthen our connection to Hashem, and re-experience the spiritual heights of Mattan Torah once again. V’chane yihi ratzon.
Shabbat shalom and chag sameach.
