If you use Google services such as Gmail, having Google Calendar manage your schedule is a logical choice, since it uses the same login information.

In the increasingly connected world that we live in, it makes sense for many people to manage their calendars online, so they can access them wherever they are and whenever they want - provided, of course, they have an internet connection.

For people already using Google services such as Gmail (Googlemail here in the UK) and iGoogle, having Google Calendar manage your schedule is a logical choice, since it uses the same login information. For users who don't already have a Gmail account, it's a good choice as well - provided that you don't mind being tied to a web browser for your calendar information.

Getting started with Google Calendar is simple. You'll need to create a Google account if you don't already have one, and then navigate your browser to google.com/calendar.

Once you've logged in, you'll be presented with a typical view of your week. Google Calendar features weekly, monthly, and daily views, as well as a customisable view that lets you choose from the next 2 to 7 days or the next 2 to 4 weeks. There's also an Agenda view that gives you a list of all upcoming events, delineated by day, just like your pen-and-paper daybook.

If you want to keep track of both work and play, you can create multiple calendars, assigning each a name and a colour to distinguish it. You can also subscribe to a variety of public calendars for events such as holidays, movie releases, and sports. If you enter your postcode, Google Calendar will even provide you with a four-day weather forecast. And surprisingly enough, unlike Google's Gmail service, Google Calendar is totally ad-free.
