Reasoning
Passage 544912, already a Temporal-reference witness on this event, is spoken during lesson 1 of the five-lesson course that this Q&A closes. Lesson 1's own delivery date is 1948-02-02 (stated, certain, catalog #1), which computes to a Monday; 'this course comes to an end on Friday' therefore places the closing session -- this event -- on the Friday of that same week, 1948-02-06. This is arithmetic on a date the packet supplies (Zeller's congruence on 1948-02-02), not an imported fact. Confidence capped at probable because the anchor date for lesson 1 is itself a legacy catalog claim, only corroborated to the year (not the day) by an independent chrome dateline.
