Backpack's Calendar is a great way for families to stay on the same page. As Marc Hedlund writes, "My wife and I use a shared Backpack calendar and it's been a huge help. We use it for social planning, appointments, reminders, and important dates." Create as many calendars as you want and color code each one (a different color for each family member perhaps?) for easy identification. Then your family's soccer practice, vacations, birthdays, and graduations can all find a home in a single calendar.
