It depends on where you are going to be and what stage load shedding it currently is. loadshedding.eskom.co.za is a great place to see your schedule. I also have Load Shed app for android installed to tell me schedules and what stage we are on.
Its not that bad a thing everyone says it is if you are prepared for it and plan your day accordingly (except if you are a business), and remember to charge your phone !
We made an app too, but the schedule is impossible to keep 100% so we have crowdsoursing
