Calendar

The calendar at Operations → Calendar unifies four sources: task due dates, project milestones, contract renewal dates, and personal events you create directly. Filters in the left sidebar toggle each source; the view (day / week / month / agenda) and chosen filters persist per user. Two-way sync with Google Calendar and Microsoft Outlook is available — see OAuth (Google & Microsoft) for connection flow and required scopes.

External invitees on a personal event receive an .ics attachment + an iCal-compatible URL on the email so their preferred calendar app handles RSVPs natively.
