Google Calendar

Google Calendar is a way to see other people's schedules and they can see yours. All you have to do is send them a request to see their calendar by typing in their email.  You can see what events they have coming up and you can add to the calendar. I think it would be really helpful to know what your family members have going on so you can build your schedule around theirs. You can set yours to show that you are available or busy on that day and what time you have that event.  It will also send you reminders if you want it too. This is a really good tool.
