The Ark — The Ark's Open Stage

Occasional.

The Ark's own events calendar, under its Open Mic category, lists four upcoming dates for The Ark's Open Stage: Monday, Aug 24; Wednesday, Sep 2; Wednesday, Sep 9; and Monday, Oct 26, 2026 [s1]. The day genuinely varies between Monday and Wednesday, never Thursday, with an uneven cadence — an established irregular schedule rather than an unknown one.
