I was 16 years old in 1975. They sure as hell promoted that date as "the end." My mother used to say we had made it "just under the wire" because my folks were baptized in 1972. My frantic father, realizing my brother and I were "of the age of reason" pushed us to get baptized, which we did in January of 1974.
To say it was implied, alluded to, but never actually said is incorrect. It was trumpeted from the rooftops while at the same time they kept saying, "but nobody knows the day or the hour." I even told my father, "Well, if every Witness picked a day and hour between now (1973) and October of 1975, somebody would get it right." Every JW believed it absolutely. Absolutely.
WTS is peopled with fiends.
