  Computer calendar programs allow users to organize appointments and events, set up digital reminders and even share events with other users of the same program. Some people spend much of their work time using their computers, and calendar programs that provide alerts are a useful way to keep track of appointments and remind users of upcoming dates to keep. Some calendar programs are free to download or offer a free trial, while others require a small fee to purchase and use.
