Record calendar events as unix time (e.g. signed 64 bit secs since 1970) and calendar type (and thus how dates are displayed) is selected in the client. You could call it "star date" (since calendars and day length were different on every planet) or "nostradate" and pick a funky origin. Java time uses 64 bit milliseconds since 1970 - that works too.
