“My father’s yahrzeit falls during the week of sheva brachos for my grandson. May I attend the sheva brachos?”
"My yahrzeit falls on Shabbos this year. Do I fast on Friday or Sunday instead?"
"I usually fast on my father’s yahrzeit, but someone is honoring me with sandaka’us on that day. Do I fast, and do I need to be matir neder in the event that it is permitted to eat?"
