Halocho #973 - Hallel on Rosh Chodesh

Today (Wednesday) is Rosh-Chodesh Shevat.

Hallel is recited on Rosh Chodesh and Mo'adim during Shacharit between the chazzan's repetition of the Amida and Reading the Torah.

One needs to stand during recitation of Hallel, which preferably should be recited with a minyan. If one comes to shul late, one joins the minyan in their recitation of Hallel, even if it's before one has prayed.

If one already started Psukay D'Zimra and the minyan begins Hallel one joins them, however one doesn’t say the Bracha before and after Hallel, relying instead on Baruch-She'amar and Yishtabach.

This applies only to days like Rosh Chodesh (excluding Tevet) when one says the "half"-Hallel.

One should not interrupt the recitation of Hallel.
