eReminder is a full-featured calendar application designed specifically for planning, managing, and scheduling your important dates and times. It runs in the background, sits in the system tray, and makes it nearly impossible to forget birthdays, anniversaries, holidays, appointments, meetings, and other important events. What's more, it provides plenty of reminding ways: play music, execute application, send Email, reboot PC, etc.
In addition to one-time occurrences, eReminder keeps track of all types of recurring events, from birthdays to meetings that you have on the third Friday of every other month.

When have finished an appointment, you can flag it with completion. When you have a lot of appointments in calendar, marking those appointments complete can give you a clear view of which appointments you still have and which appointments you have finished, and let you have full control of your time.
