Easy? Hmmm.

0 12 * * 1 [ $(expr $(/bin/date +\%s) / 60 / 60 / 24 / 7 \% 8) -eq 3 ] && myscript

works for me well enough: runs every Monday at noon and checks whether
another eight weeks have passed, and if so executes myscript. By
adjusting the -eq 3 the starting date for the eight week interval can be
shifted around.

HTH,
