Cron jobs and holidays

[Neil Watson]

How would you ensure that a cron job was not run on a statutory holiday?
My current thought was

4 4 * * 2-6 grep `date +%Y%m%d` /etc/holidays 1>/dev/null && my_script

Using this method the holidays file is kept manually.  Is there a more
elegant and automatic way?
