DayMate is a versatile intuitive day planner. This professionally developed and well designed application allows to create and schedule reminders that can pop up messages with optional sound effects; start applications or open documents; and shut down, reboot, or power down your system. DayMate can also check for new e-mail, dial phone numbers, synchronize system time via the Internet, send messages, and open a specified Web sites.
You can create single or recurring appointments, color-code different item types, set reminders for upcoming appointments, and more. A drag and drop feature allows you to easily reschedule an appointment or change its duration.
Windows XP/ Vista/ 7
These days, the big thing about planners is the ability to sync them with mobile devices. I don't see any mention of that in the program description. For me, anyway, syncing with my mobile is essential.
