The HSF Community Calendar can be edited by people in the HSF Coordination Team or in the HSF Calendar Editors Group Google Groups.

The most straight forward way to do this is to

https://calendar.google.com/calendar/ical/e4v33e1a1drbncdle1n03ahpcs%40group.calendar.google.com/public/basic.ics

Then you will have the ability to view events in the community calendar and, if you are in an editing group, add them.

Please ask to join one of the editing groups if you would like to add events for your experiment or community. Events in HSF working groups indico categories should be synced automatically.
