Students here usually get Mondays off when the next Tuesday is a holiday. As a university sysadmin, I cherish those days because that's when we can get actual work done without having to work around the chaotic classroom reservations or work in ten-minute bursts during breaks. It's also when we can implement changes to the network and update the servers because the office workers don't tend to come in.
The last time that happened, all of us sysadmins did about three months' worth of actual work in a few hours, then used the smaller lecture hall as a cinema for the rest of the day.
