You may have found yourself wondering what is an electronic calendar (or digital calendar)?
In a nutshell a digital calendar is just an electronic version of the normal, everyday calendar.
It gives you (the user) a variety of office tools such as the all-important address book, appointments, contact list and other cool applications.
To geek-speak, electronic based calendars are often contact and time management web applications that allow you to synchronize all your calendar details and information with other online users!
A really good example of an electronic or digital calendar is the Google calendar.
Other examples are the handy digital calendars you would find in Microsoft Outlook or iCal on (Apple) Mac OS X computers.

The cool thing about these e-calendars is that all the details are stored online. It's a pretty handy way to organize and manage projects when you've got a group of people working towards one common goal.
You can also synchronize some of the online calendars with mobile devices such as the BlackBerry, Palm Pilot or Pocket PC, and probably lots more too.
I predict e-calendars are going to become super popular judging by how rapidly we are evolving towards high tech, high speed, cyber communication!
If it's simple and works, we're happy!
Yahoo also has a similar online calendar.
The Yahoo calendar allows you to sync your calendar with palm device, some cellphones, share schedules between users, travel back in time (this one is coming soon) set alarms, send emails...
And do other cool online stuff with your friends really effectively!
Another online personal organizer is the gorgeous 30 Boxes, an online personal organizer with strong social networking aspects, consisting of several applications including "a critically acclaimed calendar."
