When Tisha B'Av immediately follows Shabbos (either because the 9th of Av is Shabbos or because the 9th of Av is Sunday), how and when do we make havdallah?
from my shul newsletter
No havdala on cup, no besamim.
At 9:02pm or after, say "Baruch Hamavdil Ben Kodesh L'chol" (not with brocha). Remove shoes. (We say brocha of "Borei Meorei Haish" in shul.)
Sunday night; Havdala on cup. No candle or besamim. For Havdala, one may use grape juice or wine.
Havdalah is said Sunday night after the fast, omitting the blessings on spices and the flame (the latter of which is said on its own next to a flame on Saturday night). (Shulchan Aruch OC 556)
Attah Chonantanu is said as usual Saturday night and Shmoneh Esrei is still not repeated if forgotten (OC 294:3)
