Once a year, since you can use months and days. In fact, iirc DST changes are 
known 5 years ahead (I'm sure I"ll be corrected if this is not the case) so 
one can even run a yearly cronjob to change the crontab ;)

Of course, waiting an hour during summertime is an option, as is running cron 
in a jail with /etc/localtime of the target timezone - use tzsetup(8) for that 
inside the jail (though seems overkill for the purpose).
