Scheduled wake from sleep mode / go to sleep mode

I'm using my new Pi as a digital calendar for the house, connected to a monitor in my kitchen. It would be ideal if we could schedule it to go into a "sleep mode" where it powers down the monitor when we leave for work and turns back on when we get home.
Any suggestions as to how I could do that? I was looking around on the googles and saw people talking about something called "X" and /etc/kbd/config but those directories didn't come with my NOOBs install?
Thanks everyone.

Does the Monitor have CEC power control?
CEC is a single wire bus on the HDMI cable.
Lots of AV stuff with HDMI now have CEC.

It's an old monitor with DVI connections (I'm using a HDMI to DVI cord)

For anyone looking for something like this (works real well for a display at home you don't want on overnight or whatever)
will turn it off
will turn it back on
This will put the monitor into "sleep" mode and wake it back up when needed.
you can use that easily through a cron job.
