iCal publishing lets you subscribe to your FileMaker calendar from any application that supports iCal feeds. This includes Google Calendar, Apple Calendar, Microsoft Outlook, and most other full-featured calendars. This is a one-way subscription – you can’t make changes back to FileMaker from your other calendar software.
The button below should open your built in calendar on your computer (usually Microsoft Outlook or Apple Calendar) and automatically subscribe to the soSIMPLE “Try it Live” calendar. This depends on your browser and your calendar software’s support of it. If clicking the button doesn’t work for you, right/ctl-click the button and copy the link. Then subscribe to it from inside your other calendar software.
