If today's in the month of the meeting that's just been held, this will give the date of the meeting in two months' time. Just paste it to a bash(1) prompt.
set `date '+%Y %m'` y=$1 m=${2#0} m=$((m + 2)) y=$((y + (m > 12))) m=$(((m - 1) % 12 + 1)) ((m % 2)) && day=Wed || day=Tue seq 7 | xargs -I @ date -d $y-$m-@ '+%Y-%m-%d %a' | grep $day\$
