Calendars always come in handy. Whether you are planning a schedule for your next project, manage your appointments or simply want to keep track on events you are going to take part in — to get things done in time you need a clear, simple and user-friendly time line. The more flexible your calendars are, the more effectively you can work with them. E.g. setting up your milestones, defining your deadlines and shifting your time line once unexpected problems occur. Besides, if you can get notified once the deadline is coming up or update the data once you stuck in the traffic then your calendar can turn out to be a real life-saver and boost your effectiveness.
Online calendars can also be useful if you’d like to publish your schedule or share it with your colleagues instantly — instead of sending hundreds of e-mails via a mailing list. Or if you’d like to provide your visitors with a date picker — e.g. for your web form. In fact, online calendar services, scripts, tools and software applications are useful for everybody.
