A newspaper notice announces that Neville, substituting for Dr. Frederick Bailes at the Fox-Wilshire Theater (10:30 a.m. Sunday services sponsored by the Science of Mind Church), begins a four-Sunday series on 'Awakened Imagination'; concurrently, Monday through Friday at 8 p.m. for three consecutive weeks beginning August 2, he conducts a public 15-night class at the Wilshire-Ebell Theater on the same theme.
This copy adds that the substitution is during Dr. Frederick Bailes's absence as director of the Science of Mind Church, which is sponsoring Neville's Southern California appearance, and that the concurrent Wilshire-Ebell class is a 15-night class, Monday through Friday at 8 p.m., for three consecutive weeks beginning 2 August, open to the public.

Source
clipping masthead: Los Angeles Evening Citizen-News, Saturday 31 July 1954; text says the series 'begins tomorrow'
Why
The article separately gives Monday-Friday, three consecutive weeks beginning Aug. 2, for the Wilshire-Ebell class -- a related but distinct sub-engagement not captured by this single date.
Reasoning
The clipping's own dateline (Saturday 31 July 1954) plus its statement that the series 'begins tomorrow' resolves to Sunday 1 August 1954 for the first Fox-Wilshire Sunday lecture. This is an inference from combining the masthead date with a relative word in the text, not a date stated as a single fact, so kept at 'probable' rather than 'certain'.

Reasoning
The WordPress scrape date is not evidence; the media item's own month-level clip_date is the external date evidence, kept at its own probable confidence.
between 1 August 1954 and 22 August 1954
bound · probable
Reasoning
The Saturday July 31, 1954 clipping says the Fox-Wilshire series begins tomorrow and continues for the next four Sundays, yielding August 1 through August 22. Endpoints are cadence-derived, so confidence is probable.
between 2 August 1954 and 20 August 1954
bound · probable
Reasoning
The same dated clipping explicitly says the Wilshire-Ebell fifteen-night class runs Monday through Friday for three consecutive weeks beginning August 2, yielding August 2 through August 20. The closing endpoint is cadence-derived, so confidence is probable.
