Steps to reproduce

• After configuring some campaigns with never ends activation dates, the monthly view of the calendar shows only until the end of the current month
• Unsure if this is just a display issue, or it'll effectively stop running the campaigns after the month ends

.. Logs, screenshots, gifs...

Expected results

• We need a campaign calendar accurate and as bulletproof as possible, since number of campaigns and schedules can get very complex

.. Justify non-trivial expectations with a link to a doc or a relevant discussion.
