We have a programmable thermostat for our furnace. Below is a chart that shows how we currently have it programmed:

	Weekday	Saturday	Sunday
Morning	5:45 AM/66º	8:45 AM/65º	8:45 AM/64º
Daytime	7:00 AM/57º	10:00 AM/63º	11:00 AM/64º
Evening	6:15 PM/63º	6:00 PM/63º	6:00 PM/63º
Night	10:00 PM/57º	10:45 PM/57º	10:00 PM/57º

Now, before you groan and say that 57º is too cold to sleep in, little 3 month old Ben was here for Thanksgiving, and the comment I heard a couple of times was that he slept really really well here.
