It depends on which version of DansGuardian. All recent versions (specifically the whole 2.9 series) have time/day controls per list built right in. The following shows up in the comments of several of the list files:

# Time limiting syntax:
# #time: <start hour> <start minute> <end hour> <end minute> <days>
# Example:
##time: 9 0 17 0 01234
# Remove the first # from the line above to enable this list only from
# 9am to 5pm, Monday to Friday.

If you have an older version (e.g. the 2.8 series), you may need to resort to some fanciness with a 'cron' job swapping in different DansGuardian configuration lists then restarting it.
