LDovid Hashem Ori

We begin reciting L’Dovid Hashem Ori on the first day of Rosh Chodesh (Tuesday). During Shacharis, it is recited after Shir Shel Yom (or after Borchi Nafshi on Rosh Chodesh). During Mincha, it is recited before Aleinu.

We do not recite an extra Kaddish on account of L’Dovid Hashem Ori. [During Shacharis, the Kaddish of Shir Shel Yom is recited after L’Dovid Hashem Ori.]

Some non-Chabad communities recite L’Dovid Hashem Ori at Mincha after Aleinu, or after Ma’ariv. When davening Mincha with such a Minyan, one must still recite Aleinu together with them. If one needs to defer L’Dovid Hashem Ori as a result, he should recite it before Al Tirah.
