Google Calendar can be a businesses’ best friend, which, if used correctly, can make your business and personal life more efficient. With more features than any other online calendar, Google Calendar allows you to not only keep track of events, but also share those events with others. You can access your calendar when you're away from your desk with two-way syncing to your phone or tablet, as well as use a mobile version made for small screens. It's the ideal tool for managing personal and professional schedules.
