OnTime Calendar

OnTime Calendar is a simple-to-use tool that gives you the possibility to manage a calendar with important tasks and events. It features a couple of advanced options which are intuitive enough for users less experienced with calendar utilities.

The setup operation takes little time and the only notable aspect about it is that you must have .NET Framework installed. When it comes to the interface, OnTime Calendar opts for a large window with a menu and ribbon bar, in addition to the calendar itself.

New tasks can be seamlessly put together by specifying the task name, due date, category, icon, and description. Events can be similarly created and you can also indicate the venue, start and end date and time, attendees, and recurrence.

It's possible to edit task and event properties, mark tasks as completed, create all-day events, view a separate list with all tasks, create and customize categories, as well as to perform filtered searches by taking into account the date range, event or task title, or event venue.

The calendar can be exported to XML format and later imported. Plus, you can import iZeit databases, clear the database, switch to a different GUI language, set the startup view to calendar or tasks, or ask the tool to remember the window size and position on exit.

It's also possible to change the first day of the week displayed in the calendar, show popups when hovering over days in month view, modify the default categories for events and tasks, or pick the database type (SQLite, MySQL, PostgreSQL) and location on the disk.

It didn't hog system resources in our tests, hang, crash or indicate errors. Thanks to its intuitive interface and comprehensive options, OnTime Calendar should come in handy to all users looking to manage a simple calendar with tasks and events.
