What is Google Calendar?
Google Calendar is a time-management and scheduling calendar service developed by Google. This web-based calendar can be accessed from practically any computer or mobile device with an internet connection, and you can sync your Google Calendar with your iPhone, Android and many other calendar apps.
However, you can go way beyond merely typing in the details of an appointment. For example, did you know you can add events to Calendar simply by speaking them? It works on both the PC and mobile phone. You can add extra calendars (including other people's) and these also appear on your phone.
