While Gevurot Geshem is recited on Shmini Atseret, Baqashat Geshem as an addition to the birkat ha-shanim is recited later — from the seventh of Marḥeshvan in Israel, from sixty days after the Julian-calendar autumn equinox in the diaspora. This passage is added starting in the evening, but since there is no repetition at night there is no special custom for announcing its insertion. I think that’s a shame, so I wrote a series of ma’aravot (piyyuṭim to be inserted into the ma’ariv service) to be recited on the day where we begin to request rain.
