Replying to Anybody know how to set an alarm up on a computer/laptop?

Like the title says, just want to know how i can get my computer to wake me up. I just moved into my apartment, and well i forgot my alarm clock. So i get to thinking that my computer has a clock on it, and that it must have an alarm. So far i haven't found a way to set it up. I just want to know if there is a program that i could download, or something that could wake me up in the morning. Thanks.
