For those who are mourning a parent for the requisite twelve-month aveilus, would Adar 1 and Adar 2 count as two separate months towards the twelve? Or does one year mean a full year, i.e., from Tishrei to Tishrei?
Practically speaking, if one lost a parent on 1 Ellul of last year, can they attend a wedding on 2 Av (except for it being the Nine Days), or must they wait until 2 Ellul?
