Calendar

Calendar is a simple and easy-to-use application that includes a calendar and allows you to add reminders of specific events.

You can easily view the present date by pressing the button 'Today'. You can also explore any year of the past or future by selecting the day and year from the main screen. What is more, it is very easy to add reminders. You just click on New event, select the day for that event, and type any message you wish to include. Moreover, if you need, you can set the event to be repeated every X days. Unfortunately, it doesn't have the ability to add sounds to the reminders.
In addition to this, the program is extremely simple and easy to use, although the user interface is not really attractive.
All in all, Calendar is a very simple calendar application, which, apart from the reminders, doesn't include anything else to make it worthwhile. There are much better calendars out there, which include many other useful options and are much more attractive, so I wouldn't waste my time with this one.
