Rainlendar is a desktop calendar that keeps all of your important tasks and events always visible to you. Rainlendar is highly customizable and will help you keep your life better organized.
Use the Rainlendar calendar to set up alarms for certain times, to remind you of important events. You can also snooze the alarms if you want to ignore them or be reminded later.
Using the iCalendar format, data from other calendar applications can be imported and used, so that you can transfer events between applications.
There is also the option of subscribing to online calendars so that you can share your events between computers.
