Shabbat Mevarchim: Shabbat of Blessing
What is Shabbat Mevarchim?
Rabbi Ari Enkin, "Shabbat Mevarchim," TorahMusings.com
There is an ancient custom to bless the upcoming Jewish month on the Shabbat which precedes Rosh Chodesh. These Shabbatot when the new month is blessed are referred to as Shabbat Mevarchim. A central feature of this prayer is the public announcement of the exact time the new moon, known as the molad is set to appear. The molad is the exact moment of the moon's renewal. Recall that at the concluding moments of every lunar cycle the moon is positioned directly between the earth and the sun and is completely invisible. A few hours following this occurrence the moon is once again visible, albeit only the most minute portion of it. At such time the molad the “birth” is recognized as having taken place and a new Jewish month has begun.
The prayer for the new month is conducted in a somewhat distinguished manner. It is led by the Chazzan while holding the Torah. The prayer announces the name of the upcoming month along with the exact moment the new moon is set to appear. It also serves to alerts the congregation as to which day(s) of the coming week will be observed as Rosh Chodesh. Finally, it asks that G-d renew the upcoming month with all forms of blessing. It is often carried out in an elaborate and impressive manner.
It is actually quite important that the exact time of the molad be announced. Doing so allows people to determine when the latest opportunity is for them to recite the Kiddush Levana. It also represents our efforts to familiarize ourselves with the workings of the calendar.
Indeed, we are strongly encouraged to somehow participate in the calculating of celestial matters. Yes, learning the basics of astrology is a mitzva!
Announcing the molad also recalls the ancient practice of Kiddush Hachodesh. In Temple times the new month was declared by the Beit Din based on manual calculations along with the testimony of witnesses who would have claimed to have seen the moon's renewal. It is rather essential to be standing when reciting this prayer as the ancient Kiddush Hachodesh was only acceptable if performed while standing.

(1) The following prayer יְהִי רָצוֹן, composed by Rav, head of the Babylonian yeshiva at Sura, is mentioned in the Talmud, (Maseches Berachos 16b), but not as a prayer specifically ordained for blessing the new month. It was actually a daily prayer that Rav recited each day after the regular service. The יְהִי רָצוֹן was adapted by Ashkenazi Jews as a prayer for the coming of the new month by adding the words: שֶׁתְּחַדֵשׁ עָלֵינוּ אֶת הַחוֹדֶשׁ הַזֶּה לְטוֹבָה וְלִבְרָכָה but Sephardic Jews omit the entire prayer as it is not mentioned either by Rambam or Avudraham.

(2) May it be Your will, Adonoy, our God and God of our fathers, to renew this [coming] month for us for goodness and blessing. Grant us long life—a life of peace, a life of goodness, a life of blessing, a life of sustenance, a life of bodily vigor, a life in which there is fear of Heaven and fear of sin a life in which there is no shame or disgrace, a life of prosperity and honor, a life in which there will be love of Torah and fear of Heaven, a life [in which] will be fulfilled the wishes of our hearts for goodness. Amein, Selah.

(3) The following prayer, is the actual blessing of the month. The Chazzan takes the Torah in his hands and declares:

(4) He Who performed miracles for our fathers, and redeemed them from slavery to freedom, may He redeem us soon and gather our dispersed from the four corners of the earth; united in friendship is all of Israel! And let us say, Amein.

(5) The new month of (name the month), which will be on (name the day or days) will come to us and all Israel for goodness.

(6) May He renew it, the Holy One, blessed is He, for us and for all His people, the House of Israel, for goodness and blessing for happiness and for rejoicing, for deliverance and for consolation, for plentiful sustenance, and support, for good life and for peace, for good tidings, and for good news, for rain at the proper time, for total recovery, and for early redemption, and let us say, Amein.

Where does announcing come from?

(א) א) [סעיף א'] ראש חדש וכו' שבת קודם ר"ח אחר קריאת ההפטרה קודם אשרי מכריז ש"צ ומודיע להקהל באיזה יום יחול ר"ח או אם יהיה יום א' או שני ימים. אבודרהם. כנה"ג סי' רפ"ד בהגב"י. מ"א סק"א.

Rosh Chodesh: The Shabbat before the upcoming beginning of the new month, after the reading of the Haftorah portion, but before ashrei, the Service Leader announces day of Rosh Chodesh and whether it will last one or two days.

(א) (א) ר"ח וכו' - מנהג קדמונינו לברך את החודש בשבת שלפני ר"ח חוץ מלפני ר"ח תשרי ורמז לזה בכסה ליום חגנו. ויש מקומות שאין נוהגין לברך ר"ח אב משום שהוא חודש של פורעניות. ואין ברכת ר"ח כקידוש החודש שהיה מלפנים אלא שמודיעים להעולם מתי יחול ר"ח ויזהרו בכל הלכות החודש. ומ"מ נהגו לעמוד בשעת אמירת ר"ח פלוני ביום פלוני דוגמת קידוש החודש שהיה מעומד [מ"א]:

Rosh Chodesh: It was the custom of our ancestors to bless the month on the Sabbath before Rosh Chodesh, except before Rosh Chodesh Tishrei, and allude to it in the case of the day of our holiday. There are places where it is not customary to bless Rosh Chodesh Av because it is a month of persecution. And there is no blessing of the New Year as the sanctification of the month that was before, except that the world is informed when the New Year will come and they will be careful in all the laws of the month. It is customary to stand during the recitation of the Rosh Chodesh blessing as the Service Leader on such and such a day, for example the Kiddush of the month he was standing (according to Midrash):

Rabbi Ari Enkin, "Shabbat Mevarchim," TorahMusings.com
There is one month, however, that is excluded from the cycle of Shabbat Mevarchim prayers and that is the month of Tishrei. Among the many explanations as to why this so, it is said that the month of Tishrei with all its holidays and their accompanying mitzvot is inherently blessed. It is as if God Himself is the one who blesses the month of Tishrei. The other months of the year which don’t contain nearly as much mitzvot as Tishrei are therefore dependant upon the Jewish people to bless them.
While in our day Tishrei is the only month for which Shabbat Mevarchim prayers are not recited, there was once a custom to omit them for the month of Av, as well. While no longer practiced, the idea for omitting the prayer on behalf of the month of Av was related to that month's eternal association with bad fortune and tragedy. It is actually the opposite reasoning that has prevailed however being that the month is so associated with tragedy, how much more so does it require our prayers!
אָמַר רַבִּי שִׁמְעוֹן בֶּן פַּזִּי, אָמַר רַבִּי יְהוֹשֻׁעַ בֶּן לֵוִי מִשּׁוּם בַּר קַפָּרָא: כָּל הַיּוֹדֵעַ לְחַשֵּׁב בִּתְקוּפוֹת וּמַזָּלוֹת וְאֵינוֹ מְחַשֵּׁב, עָלָיו הַכָּתוּב אוֹמֵר: ״וְאֵת פֹּעַל ה׳ לֹא יַבִּיטוּ וּמַעֲשֵׂה יָדָיו לֹא רָאוּ״. אָמַר רַבִּי שְׁמוּאֵל בַּר נַחְמָנִי אָמַר רַבִּי יוֹחָנָן: מִנַּיִן שֶׁמִּצְוָה עַל הָאָדָם לְחַשֵּׁב תְּקוּפוֹת וּמַזָּלוֹת — שֶׁנֶּאֱמַר: ״וּשְׁמַרְתֶּם וַעֲשִׂיתֶם כִּי הִיא חׇכְמַתְכֶם וּבִינַתְכֶם לְעֵינֵי הָעַמִּים״, אֵיזוֹ חָכְמָה וּבִינָה שֶׁהִיא לְעֵינֵי הָעַמִּים — הֱוֵי אוֹמֵר: זֶה חִישּׁוּב תְּקוּפוֹת וּמַזָּלוֹת.
Rabbi Shimon ben Pazi said that Rabbi Yehoshua ben Levi said in the name of bar Kappara: Anyone who knows how to calculate astronomical seasons and the movement of constellations and does not do so, the verse says about him: “They do not take notice of the work of God, and they do not see His handiwork” (Isaiah 5:12). And Rabbi Shmuel bar Naḥmani said that Rabbi Yoḥanan said: From where is it derived that there is a mitzva incumbent upon a person to calculate astronomical seasons and the movement of constellations? As it was stated: “And you shall guard and perform, for it is your wisdom and understanding in the eyes of the nations” (Deuteronomy 4:6). What wisdom and understanding is there in the Torah that is in the eyes of the nations, i.e., appreciated and recognized by all? You must say: This is the calculation of astronomical seasons and the movement of constellations, as the calculation of experts is witnessed by all.
Why Shabbat?
גְּמָ׳ מַאי שְׁנָא שֵׁנִי מַתְקִיעַ — מִשּׁוּם דִּ״בְרוֹב עָם הַדְרַת מֶלֶךְ״, אִי הָכִי הַלֵּל נָמֵי — נֵימָא בַּשֵּׁנִי מִשּׁוּם דִּ״בְרוֹב עָם הַדְרַת מֶלֶךְ״!
GEMARA: The Gemara asks: What is different about the second prayer leader, that he sounds the shofar during the additional prayer? Is it due to the principle that: “The splendor of the King is in the multitude of the people” (Proverbs 14:28)? In other words, is the shofar sounded during the additional prayer because all of the congregants will have arrived by then? If so, with regard to hallel too, let us say that it should be read by the second prayer leader, due to the principle that “The splendor of the King is in the multitude of the people.”
גְּמָ׳ אָמַר רַבִּי יִצְחָק: אֵין הַפֶּסַח נִשְׁחָט אֶלָּא בְּשָׁלֹשׁ כִּתּוֹת שֶׁל שְׁלֹשִׁים שְׁלֹשִׁים בְּנֵי אָדָם. מַאי טַעְמָא? ״קָהָל״ וְ״עֵדָה״ וְ״יִשְׂרָאֵל״. מְסַפְּקָא לַן אִי בְּבַת אַחַת אִי בְּזֶה אַחַר זֶה, הִלְכָּךְ בָּעֵינַן שָׁלֹשׁ כִּתּוֹת שֶׁל שְׁלֹשִׁים שְׁלֹשִׁים בְּנֵי אָדָם. דְּאִי בְּבַת אַחַת — הָא אִיכָּא, וְאִי בָּזֶה אַחַר זֶה — הָא אִיכָּא, הִלְכָּךְ בְּחַמְשִׁין נָמֵי סַגִּיא, דְּעָיְילִי תְּלָתִין וְעָבְדִי, עָיְילִי עַשְׂרָה וְנָפְקִי עַשְׂרָה, עָיְילִי עַשְׂרָה וְנָפְקִי עַשְׂרָה.
GEMARA: Rabbi Yitzḥak said: The Paschal lamb is slaughtered only in three groups of at least thirty people each. What is the reason for this rule? The verse says: Assembly, congregation, and Israel, and each of these terms refers to a group of no fewer than ten people. We are uncertain as to whether this means that we need three groups of ten people at the same time or one after another. Therefore, in order to satisfy both possible interpretations, we require three groups of thirty people each. As, if you say we need all thirty at the same time, we have that, and if we need them one after another, we have that as well. Therefore, in pressing circumstances when there are not enough people present, even fifty people suffice. How so? Thirty enter and perform the necessary rite, ten others enter and ten of the original group leave so that those present are considered a new group, and then ten others enter and ten more leave so that those present now comprise a third group. In this way the Paschal lamb is slaughtered in three groups of thirty people each, although the total number of people involved is only fifty.
ממאי דלמא עד כאן לא קאמר ר' ישמעאל הכא אלא דליכא פרסומי מילתא אבל התם דאיכא פרסומי מילתא אימא כרבנן סבירא ליה
The Gemara rejects this comparison: From where is this conclusion reached? Perhaps Rabbi Yishmael states his ruling only here, because there is no greater publicity of the event achieved by using five se’a rather than three. But there, in the case of reaping the barley, where there is greater publicity of the event through the involvement of more people, one can say that he holds in accordance with the opinion of the Rabbis.

(1) FESTIVALS AND SEASONS OF THE YEAR: Rosh Chodesh — The New Moon
The force which draws all the worlds to return to God has its root on Rosh Chodesh, the New Moon. On Rosh Chodesh the desire to return to God is felt over the entire creation. Even the sinners in hell cannot escape a certain feeling of contrition. They are drawn a little closer to God and feel a flicker of regret. They are forced to acknowledge the truth and feel ashamed of their wrongdoing (10:9).

ובו סעיף אחד:
ראש חודש מותר בעשיית מלאכה והנשי' שנוהגות שלא לעשות בו מלאכה הוא מנהג טוב הגה ואם המנהג לעשות מקצת מלאכות ולא לעשות קצתן אזלינן בתר המנהג: (ב"י)
On the beginning of the month, it is permitted to do work. However, those women who follow a custom to not engage in work [are following] a good custom. Rema: And if the custom is to do some kinds of work and not to do some [other] kinds of work, we follow the custom.
(כז) נֵ֣ר יְ֭הֹוָה נִשְׁמַ֣ת אָדָ֑ם חֹ֝פֵ֗שׂ כׇּל־חַדְרֵי־בָֽטֶן׃

(27) A light of G-d is the soul of a person; Revealing all their innermost parts.*

*could be translated to mean womb

(טז) וַיַּ֣עַשׂ אֱלֹהִ֔ים אֶת־שְׁנֵ֥י הַמְּאֹרֹ֖ת הַגְּדֹלִ֑ים אֶת־הַמָּא֤וֹר הַגָּדֹל֙ לְמֶמְשֶׁ֣לֶת הַיּ֔וֹם וְאֶת־הַמָּא֤וֹר הַקָּטֹן֙ לְמֶמְשֶׁ֣לֶת הַלַּ֔יְלָה וְאֵ֖ת הַכּוֹכָבִֽים׃ (יז) וַיִּתֵּ֥ן אֹתָ֛ם אֱלֹהִ֖ים בִּרְקִ֣יעַ הַשָּׁמָ֑יִם לְהָאִ֖יר עַל־הָאָֽרֶץ׃ (יח) וְלִמְשֹׁל֙ בַּיּ֣וֹם וּבַלַּ֔יְלָה וּֽלְהַבְדִּ֔יל בֵּ֥ין הָא֖וֹר וּבֵ֣ין הַחֹ֑שֶׁךְ וַיַּ֥רְא אֱלֹהִ֖ים כִּי־טֽוֹב׃
(16) God made the two great lights, the greater light to dominate the day and the lesser light to dominate the night, and the stars. (17) And God set them in the expanse of the sky to shine upon the earth, (18) to dominate the day and the night, and to separate light from darkness. And God saw that this was good.
וא"ר אחא בר חנינא א"ר אסי א"ר יוחנן כל המברך על החדש בזמנו כאילו מקבל פני שכינה כתיב הכא (שמות יב, ב) החדש הזה וכתיב התם (שמות טו, ב) זה אלי ואנוהו תנא דבי רבי ישמעאל אילמלא (לא) זכו ישראל אלא להקביל פני אביהן שבשמים כל חדש וחדש דיים אמר אביי הלכך נימרינהו מעומד
And Rabbi Aḥa bar Ḥanina says that Rabbi Asi says that Rabbi Yoḥanan says: With regard to anyone who blesses the new month in its proper time, it is as if he greets the Face of the Divine Presence. Alluding to this, it is written here concerning the sanctification of the new month: “This month shall be for you the beginning of months” (Exodus 12:2), and it is written there, where the Jewish people encountered the Divine Presence at the splitting of the sea: “This is my God and I will glorify Him” (Exodus 15:2). The term “this” is employed in both verses. The school of Rabbi Yishmael taught: If the Jewish people merited to greet the Face of their Father in Heaven only one time each and every month, it would suffice for them, since in the blessing of the moon there is an aspect of greeting the Divine Presence. Abaye said: Therefore, we will say the blessing while standing, in honor of the Divine Presence.
Gershom Scholem, On the Kabbalah and its Symbolism, 151-153
This 'lessening of the moon' was interpreted by the Kabbalists as a symbol of the Shekhinah's exile. The Shekhinah itself is the 'holy moon,' which has fallen from its high rank, been robbed of its light and sent into cosmic exile. Since then, exactly like the moon itself, it has shone only with reflected light. With the Talmudic explanation, which relates only to the designation of the moon as the 'lesser light' in the first chapter of Genesis, the Kabbalists connected their knowledge of the changing phases of the moon, which seemed to indicate that until the Messianic redemption the moon (and the Shekhinah as well) would time and time again sink back into utter lightlessness and want. Only in redemption would the moon be restored to its original state, and in support of this belief a verse from Isaiah (3o : 26) was cited. Meanwhile, no cosmic event seemed to the Kabbalists to be more closely connected with the exile of all things, with the imperfection and the taint inherent in all being, than this periodic lessening of the moon.
Kabbalah looks at the moon-Jew connection in a whole new light. The mystics see the sun as the generator of two types of light: an external and obvious light that functions to illuminate the earth and generate photosynthesis, and a second, “internal” light. The internal light is not necessarily about performing; it’s just about being. It’s too sublime to be exposed directly from the sun; it presents itself only through the medium of the moon’s reflection. Although the light of the moon seems weaker than the direct sunrays, its light actually displays the sun’s essential light.
