22 A place that is accustomed to do work on Tisha B'av, one can do. A place that is accustomed that they do not do work on Tisha B'av, one should not do. In all places, Talmud Chachim (Torah Sages) are idle (i.e. from work), and all who want to make themselves a Talmud Chacham regarding this matter, one can do. Even in a place that is accustomed not to do work, it is allowed via a Gentile even in his (the Jew's) house. (Regarding) doing business for profit or to get wages (i.e. as opposed to for preventing loss etc.), in a place that is accustomed not to do work, it is forbidden. In a place that is accustomed to do work, it is permitted. However, that it should be minimized, as even upon the entry of (the month of) Av, we reduce transactions. Rema: It is not the custom in forbidding work except until Halachic Noon [Minhagim]. It is the custom to be strict until Halachic Noon in all work that there is some delay even a non-professional act. But something that does not have delay like lighting a candle, tying (a knot) and similar are permissible. Milking cows, it is good to do via a Gentile if possible with a Gentile.
