I am currently using Rainlendar, which is not able to sync with online Google Calendar.
Is there any software that can display my events and to-do list on my desktop and sync with online Google Calendar?
There are multiple desktop calendars that are able to synchronize with Google Calendar, but before switching to a different application, you could try using GCALDaemon, which offers two ways of synchronization between Google Calendar and various compatible calendar applications. GCALDaemon is able to perform a file-based synchronization between Google Calendar and Rainlendar. For more information about this software, go to http://gcaldaemon-beta-16.software.informer.com/ If it's easier for you to use a program that is already synchronized with Google Calendar, you can try Desktop iCalendar Lite( http://desktop-icalendar-lite.software.informer.com/ ) or VueMinder Calendar Pro( http://vueminder-calendar-pro.software.informer.com/ )
