Joseph Karo 548: The Laws of Mourning on Hol Hamoed…

Paragraph 6 - Even though there is no mourning during the holiday, if somebody experiences a death on the holiday, we occupy ourselves with comforting him on the holiday. After the holiday, once seven days have passed since the dead, even though the mourning period has not finished, his work can be performed by others in their house and his servants can work in the privacy of his home.

Joseph Karo 548: The Laws of Mourning on Hol Hamoed…

Paragraph 20 - If ten days after Sukkot, he finds out that somebody died the day before Sukkot, even though if we were to count the hour before the holiday as seven, the seven days of Sukkot and Shimi Atzeret, together twenty one days, and the ten days afterwards, we would have thirty days, this is treated not as distant news but as recent news. The holiday does not count for one who did not practice any mourning prior to it; how much more so somebody who didn't even know about the death.
