How often you change your stings all depends on how often you play and what type of strings you use. As you play a set of stings they will slowly lose their tone due to stretching and oil and dirt buildup. The sound of the strings may be the deciding factor in changing them.

You can preserve the tone of your strings somewhat if you clean your hands before playing the guitar and clean the strings after you are done. You can buy string cleaning formulas, but wiping them with a clean dry cloth should do. My hands build up a bit of a sweat when I’m playing for long periods of time, so cleaning that off really prolongs the life of my strings.

I have heard you should be able to expect anywhere from 12 hours of play and up depending on what types of strings. Now 12 hours of play isn’t very much. If you play 2 hours a day that’s once a week you would have to change your strings. Basically what that time means is after 12 hours of play the strings will start to lose their initial tone. If you are playing gigs or are a touring musician, that might be required for you, but for the average Joe its overkill.
