His practical, unsuperstitious businessman brother treats the thirteenth as his lucky day because his father's blow, his own new business, his marriage and his building purchase all fell on the 13th of the month.
Date (happened)
before 1966
bound · possible
Reasoning
Qualifying passage ids [547391] belong to telling lecture nids [1868]. Each listed lecture contributes the selected safe envelope year 1966 (MAX of its non-refuted delivery years); 1966 is the MIN across telling lectures.
before 18 February 1966
bound · probable
Reasoning
The pattern (four life milestones all falling on the 13th) has no single happening date, but it must predate the telling; the lecture's delivery date is now corrected to 1966-02-18 (stated/probable), sharpening the existing year-level 'before 1966' envelope bound to day precision.
Told
18 February 1966
estimated · probable
Reasoning
The brother's thirteenth-day pattern is undatable as a single occurrence; what is datable is the telling, which the corrected lecture dateline places at 1966-02-18.
