How communities differ

Skipped in practice

• Korbanot — first block dropped when late; internal priority Parashat HaTamid > Ketoret > Eizehu Mekoman. Mourners omit Korbanot entirely.
• Pesukei DeZimra trimmed per SA OC 52: Ps. 148, then 149, then the body, keeping Barukh She'amar → Ashrei → Yishtabaḥ.
• Nishmat dropped before the body of Pesukei DeZimra on Shabbat when pressed.
• Taḥanun on roughly 40 days a year (see the tachanun omission table).
• Berikh Shemei omitted by some weekday minyanim.
• Heicha Kedushah at weekday Minḥah in workplace and yeshivah minyanim.

Never skipped

• Birkhot Kri'at Shema — semikhat ge'ulah li-tefillah outranks praying the Amidah with the congregation.

Added

• Prayer for the government, the State of Israel and the IDF between the Haftarah and returning the scroll
• Torah readings for Yom HaAtzma'ut and Yom Yerushalayim

Skipped in practice

• Korbanot — absent from the order entirely.
• The Hodu / 1 Chronicles block and Ps. 100 in Pesukei DeZimra.
• The Vayvarekh David / Az Yashir material.
• Yekum Purkan, Av HaRaḥamim, An'im Zemirot — not in the Shabbat morning contents.
• Most piyyutim and yotzrot.
• Musaf often reduced to the silent Amidah plus an abbreviated repetition and Kedushah.
• Taḥanun on any day 'deemed even slightly joyous'; Psalm 20 likewise.

Textual alterations

• Musaf sacrifices in the past tense: asu v'hikrivu, not na'aseh v'nakriv (1927; retained through Sim Shalom and Lev Shalem). No petition for restoration.
• Birkhot HaShaḥar: she-asani Yisrael / she-asani ben-ḥorin / she-asani be-tzalmo.
• Imahot bracketed after avoteinu, with full matriarch alternatives — an option, not a replacement.
• Meḥayeh ha-kol offered in parallel with meḥayeh ha-metim.
• 'Ishei Yisrael' omitted from Retzeh in the weekday edition.
• Birkhot HaShaḥar ordered per Nusaḥ Sefard.

Retained (contrary to assumption)

• V'haya im shamoa, the second paragraph of Shema — retained. Omitting it is Reform/Reconstructionist practice, not Conservative.
• Rabbi Yishmael's baraita — retained, with alternative closing texts.
• Taḥanun — retained.

Practical spine

Birkhot HaShaḥar (abbreviated) → Barukh She'amar → Ashrei → Ps. 146-150 → Nishmat → Yishtabaḥ → Barekhu → Shema → Amidah → Torah service → Musaf → Aleinu → Adon Olam.

Vocal character

Markedly more congregational unison singing, responsive English readings and ḥazzan-led melody than Orthodox practice. Kedushah functions as a responsive reading. Mourner's Kaddish typically said standing by the whole congregation.

Omitted

• Bameh Madlikin — replaced by Kegavna.
• Barukh Hashem L'Olam at weekday Ma'ariv — and a Chabad Jew does not say it even in a congregation that does (Sefer HaMinhagim).
• 'Or ḥadash al Tziyon ta'ir' in Yotzer Or, following R. Saadiah Gaon.
• An'im Zemirot / Shir HaKavod — not printed at all.
• Yigdal and Adon Olam as closing hymns.
• Shabbat zemirot — niggunim or a ḥasidic ma'amar instead.
• The Ushpizin invitation.
• Yekum Purkan — first paragraph only.
• The prayer for the government and the prayer for the State of Israel — absent from the Chabad order.

Added

• Hodu before Barukh She'amar; Ps. 98 added; Ps. 121-124 reordered.
• Ketoret recited twice daily.
• Ein Keloheinu + Pittum HaKetoret + Kaddish d'Rabbanan DAILY, not only Shabbat.
• After Shaḥarit: Shir shel Yom → Hoshi'einu (year-round) → the psalm corresponding to one's age → the daily Tehillim portion.
• Rabbeinu Tam tefillin daily from bar mitzvah, after Shaḥarit, without a berakhah.
• The Six Remembrances daily, all year.

Textual alterations

• Kaddish adds v'yatzmaḥ purkanei vikarev meshiḥei.
• Shaḥarit Kedushah opens Nakdishakh v'na'aritzakh, not Nekadesh et shimkha.
• Musaf Kedushah opens KETER YITNU LEKHA, plus Hu yoshi'einu v'yig'aleinu sheinit b'karov.
• Kedushah per the Arizal: congregation says the connective passages quietly first, leader then repeats aloud.
• Answers Amen where Ashkenaz answers Brikh hu; says Barukh Hu u-varukh Shemo broadly; bows right-first at Oseh shalom.
• Hagbahah before the reading, not after. Berikh Shemei on Shabbat and Yom Tov only.

Additional Taḥanun omissions

• 10 Kislev
• 19-20 Kislev
• 12-13 Tammuz — each from the preceding afternoon

Hoshanot

After Hallel, not after Musaf. One hakafah daily, seven on Hoshana Rabbah. Not said on Shabbat.

Seliḥot

From 1 Elul through Yom Kippur, but during the Ten Days only on the Fast of Gedaliah. Ashamnu Bagadnu once per day only.

Vocal character

The minyan formally begins aloud at Hodu rather than Barukh She'amar. Much of Pesukei DeZimra is at each person's own pace, quietly — noticeably more silent and less unison-sung than other nusaḥim.
