When do you turn off your Ubuntu boxes?

[Peter Hummers]

I found this on Digg, about the energy-saving aspects of turning 
computers off when not in use (/not/ about the software, which is 
Windows only):

On Un*x, I've always left my computer on overnight (actually, for months 
at a time) to let cron do its housekeeping, but I see that Ubuntu 
installs anacron, which will complete the same tasks according to time 
elapsed since the last instance, not absolute time (i.e. 15:00).

How often do you all turn off your desktop Ubuntu boxes?
