Based on the sources in the footnote below it would seem that the time for aveilus is either from Rosh Chodesh Av or during the week of Tisha B’av.7 However, many poskim among them the Rama bring down that the time of aveilus starts from Shiva Asar B’tamuz.8

Night Before or in the Morning

There is a discussion among the poskim if one has to refrain from the actions which are not done during the three weeks from the morning of Shiva Asar B’tamuz or even the night before? Most poskim say that one should refrain from doing these activities even from the night before,9 from tzeis.10 In a pressing situation one can be lenient (i.e. wedding on Motzei Shabbos).11 

Some are of the opinion that during ben hashmoshes one can be lenient with the actions which are customarily refrained from during the three weeks (i.e. haircut).12

There is a minority view that holds that some have the custom not to eat meat from Shiva Asar B’tamuz until after Tisha B’av,13 (except for Shabbos),14 but the custom is not like this. Some have the custom to fast each day from Shiva Asar B’tamuz until after Tisha B’av,15 but the custom is not like this, especially for one who teaches Torah and is concerned it will affect his learning.16
