4) When Tisha B'Av is a nidcheh, all restrictions are permitted immediately with the conclusion of the
fast on Sunday night [including bathing, shaving, music, etc...], with the exception of consuming wine
[other than for Havdala] and meat, which become permitted at daybreak of Monday morning.
If the ninth of Av falls on Shabbat, in which case the fast is delayed until the tenth, many of the restrictions applicable to the Nine Days end when the fast ends, and havdalah wine, music, bathing and haircutting are permitted. We do not eat meat or drink other wine until the next morning, however.
