Object
Major Daly's Cabin Wall Calendar
Distinct from the cabin's door lock; tracks temporal anomalies through visible calendar dates up to June 4th, 1926
3 appearances
Purpose
Used aboard the SS Bernice to track the ship's sailing dates, setting the chronological baseline for the calendar's role as a temporal anchor in reality-divergent events
Significance
The calendar's internal conflict with the observable clock forces the Doctor to realize they are trapped in a 1926 time loop aboard a vessel that officially vanished decades earlier. Its dates become pivotal evidence of the ship's unnatural existence and the Doctor's deduction of cosmic tampering
