Multiple Relays controlled by clock Arduino Answered

A friend has a project in mind that involves an arduino controlling multiple relays with the use of a clock.

He would like to be able to control each individual relay, and would like to be able to have a different time schedule every day of the week. There would be times where more than one relay is activated, and times when none are.

How could this be done? 
Could someone direct me in the direction I should be looking? Not sure what to look for here (Most of what i found only works on 24 hour loops)

How familiar are you (or your friend) with Arduino? I think the way to go would be to use a RTC (Real Time Clock) to keep track of the time, then it would be simple to enter your schedule and have it turn on and off the relays when you want them to.
