ההלכה מוקדשת לעלוי נשמת
כל הנרצחים בפרעות שביצעו צוררי נפשינו
ארץ אל תכסה דמם, וכן לרפואת הפצועים, ולזכות השבויים האומללים, ולהצלחת חיילי ישראל בכל מקום שהם, ה' יתברך יעמוד לימין צדקם, וימגר את כל אויבינו, לא יותיר בהם נשמה, המה יאבדו ואנו נעמוד לעד לעולם עד ביאת משיח צדקינו במהרה בימינו אמן.

Inserting “Ya’aleh Ve’Yavo” into the Rosh Chodesh Prayers
Our Sages instituted that one add the “Ya’aleh Ve’Yavo” text (printed in Siddurim) into the prayers and Birkat Hamazon of Rosh Chodesh.
One who Forgets to Insert “Ya’aleh Ve’Yavo” on the Night of Rosh Chodesh
If one forgets to add “Ya’aleh Ve’Yavo” on the night of Rosh Chodesh, either on the first night or the second, one does not repeat the Amida prayer. (The reason for this is discussed in the Gemara, Masechet Berachot 30b, which is that the new month is not sanctified at night.)
Even if one remembers that one has forgotten to insert “Ya’aleh Ve’Yavo” before concluding one’s prayer, he may not return to “Retzeh” and add “Ya’aleh Ve’Yavo” since the law is that one who forgets to mention “Ya’aleh Ve’Yavo” in the Arvit prayer does not go back and this does not impede one’s prayer; thus, one would not be permitted to recite “Ya’aleh Ve’Yavo” unless one has not yet recited the words “Baruch Ata Hashem” of the “Ha’Machazir Shechinato Le’Zion” blessing. However, once one recites the words “Baruch Ata Hashem”, one may no longer go back and recite the “Ya’aleh Ve’Yavo” text and one must conclude the blessing by saying “Ha’Machazir Shechinato Le’Zion” and proceed to conclude the Amida. (Responsa Yabia Omer, Volume 1, Chapter 22, Section 13 and Chazon Ovadia-Chanukah, page 260)
One who Forgets to Insert “Ya’aleh Ve’Yavo” in the Other Rosh Chodesh Prayers
If one forgets to add “Ya’aleh Ve’Yavo” in the other prayers of Rosh Chodesh, namely Shacharit and Mincha, and remembers on after concluding the prayer, one must then repeat the Amida prayer. If one remembers after reciting the words “Baruch Ata Hashem” but before reciting the words “Ha’Machazir Shechinato Le’Zion”, one should immediately insert the words “Lamedeni Chukecha” (which would mean that one would have recited a verse from Tehillim: “Baruch Ata Hashem Lamedeni Chukecha”) and then go back and add “Ya’aleh Ve’Yavo.”
If one remembers after reciting the words “Ha’Machazir Shechinato Le’Zion” but before reciting the word “Modim”, one should insert “Ya’aleh Ve’Yavo” right there, in between the two blessings (until the words “Ki El Melech Chanun Ve’Rachum Ata” and the continue with “Modim”).
However, once one begins the blessing of “Modim”, one will no longer be able to insert “Ya’aleh Ve’Yavo” in any place one remembers. Rather, one must return to the beginning of the “Retzeh” blessing and continue on as usual from that point on including the addition of “Ya’aleh Ve’Yavo.”
If one has already concluded one’s prayer by reciting the final “Yihyu Le’Ratzon Imreh Fi Ve’Hegyon Libi Lefanecha Hashem Tzuri Ve’Go’ali” of the Amida prayer (which follows the “Elokai Netzor” section) and only then realizes that one has forgotten to insert “Ya’aleh Ve’Yavo”, one must repeat the entire Amida prayer with intense concentration so as not to forget to add “Ya’aleh Ve’Yavo” once again. (Chazon Ovadia-Chanukah, page 265)
If one forgets to insert “Ya’aleh Ve’Yavo” in the Birkat Hamazon of Rosh Chodesh, one does not repeat Birkat Hamazon.
