**I want t**o see my project calendar in my personal calendar

**So that** I don't have to maintain two different calendars to organize my work.

# Use case examples

1. Release dates and other project milestones
2. Submission deadlines of artefacts that require collaboration with other team members
3. Extend certificats (e.g. SSL, SMIME) 

End of the insertion While trying to introduce OpenProject in a team that I’m part of, I realised that there is no way to integrate the calendar with MS Outlook, Apple Calendar, Google Calendar, and the likes. It would greatly increase the visibility of project planning if people were able to see changes in their preferred calendar apps, instead of having to check the OpenProject calendar webpage. Export functionality would provide a very natural means to integrate OpenProject with existing planning and coordination routines established in teams (most of which will be using a calendar app of sorts).

Actually Calendars in OpenProject are project based (an overall view over all projects or the projects an user has access to) is not provided. Further users may have other calendars (business and/or private) they want to have a merged view on their (mobile) devices. Therefore exporting publishing OpenProject Calendar data by the well supported CalDAV protocol would be very appreciated. Hereby an user can:

* select (filter) in here user preferences which aspects (project status, type of tasks/meetings, date range) of the calendar she wants to be subscribed to
* CalDAV access may be read only
