Yosef Karo

“ If one of the days of mourning, other than the seventh, falls on the eve of the festival, he is permitted to launder, but he should not wear it [i.e. the newly laundered clothing] until the evening. And it is good to refrain from washing until after noon in order that it will be recognizable that it is because of the festival that he is washing. But to bathe is forbidden until the night. And there are those who permit bathing after praying minchah close to darkness. ”

“ One who buries one’s dead before a festival, such that he became subject to mourning and he started practicing [the customs of mourning] even for one hour [i.e. a short time] before the festival, the period of mourning stops and the laws of shiva are canceled and the days of the festival count for him towards the counting of sheloshim – that is, he has seven before the festival, the days of the festival and then he completes on top of those days the rest of sheloshim. ”

“ And people engage in comforting him during the festival. (Gloss: And all work is permitted to be done on the festival to prevent a financial loss by himself. But if it is not devar haaved, it is done by others in their homes, and his servants do it privately in his house.) And after the festival, he begins to count shiva, and at the end of seven days from the time of death, even though the seven days of mourning have not finished yet, his work can be done by others inside their homes and his servants mat do [work] for him privately within his home. ”
