Imagine being at the dentists office, hair stylist, or planning a get together. You would like to know if your significant other can watch the kids, but you can't get them on their cell phone. You might schedule something, only to find out your spouse scheduled something at the exact same time for both of you. For years businesses have used calendar applications to keep companies out of this sort of conflict, but now it is possible for a family to do everything that business could do, and more with calendar applications such as Google Calendar. It's free, it's fun, and although it takes a little setup, once the setup is done it is wonderful!
