Smartphones and online calendars have certainly made it easier to get a handle on your daily schedule, and if you’ve gotten used to the concept of calendar events and alerts from your office or job, think of how handy these could be for keeping track of your family’s whereabouts. You can do this by setting up a shared online calendar to use for appointments, and all your family members can subscribe to it on their own smartphones and computers. When someone enters a a new event on that shared calendar, everybody else subscribed to the calendar then sees it — hopefully clearing up confusion about who’s doing what on any given day.

Sure, you can find plenty of third-party solutions like Cozi or the HUB Planner that have limited free versions and more expansive paid plans, but if your family’s needs are not complex – say, you just need to keep track of softball practice, book club, dentist appointments and so on – you might be able to get by with software you already have: The calendar component to your free email service.

For example, Microsoft has ways to share calendars using Outlook and Outlook.com. Yahoo Calendars can also be shared with family members.

Now, for iCloud. If you are an Apple-oriented group of people, you can share an iCloud calendar with others, but you don’t have to stop with just the datebook. If you have kids with their own iDevices wanting to buy stuff on iTunes, you can even set up Apple’s Family Sharing feature that lets parents approve their children’s iTunes and App Store purchases remotely, share photos and location — and yes,  there’s a family calendar.

Don’t worry, Android folks, if you’re tapped into the Google Play store and spurn iTunes, there’s also a family management tool to set up and you can always use the Android Device Manager to GPS your child’s location. If you’re a Gmail family as well, check out sharing with Google Calendar.

It may take a little work to get used to having a family calendar and entering events on it, but once it’s in place, perhaps those days of forgetting to pick up Junior from soccer practice (whoops!) will be a distant memory.
