Yang Bing-yi founded Din Tai Fung in Taipei in 1958, first as a cooking-oil retailer and then as a dumpling house when the oil business failed. Its xiaolongbao, pleated to a standard count of folds, turned a single shop on Xinyi Road into a chain across Asia and the United States.

Harry Barberian opened his steak house on Elm Street in 1959, in a row of Victorian houses behind Yonge Street, and it has outlasted most of what grew up around it - a dark room of oil paintings and charcoal-grilled beef with one of the deepest wine cellars in Canada dug out beneath it.

A magnitude 9.5 megathrust rupture off southern Chile shook for ten minutes — the strongest earthquake ever instrumentally recorded. Its tsunami crossed the Pacific and struck Hilo, Hawaii, with waves 10.7 m high.
ESTIMATED70% CONFIDENCEWikipedia[3], the Henry Ford museum and Guinness World Records[2] all date the first Unimate installation to 1961, but none give a specific month or day.
In 1961 General Motors installed the Unimate, the world's first industrial robot, at its New Jersey factory to lift and stack hot die-cast metal parts. Industry 4.0 opens its history of factory automation with this machine.

Sam Walton opened Wal-Mart Discount City on Rogers' Highway 71, his first store under the name after a decade running Ben Franklin variety stores. The format was the bet: lower margins on everything, in towns the big chains had written off as too small.

Opel opened its Dudenhofen proving ground near Frankfurt in April 1966, the most modern car test center in Europe at the time. Six decades on, its more than 70 kilometers of track still put prototype technologies like automated driving through secretive testing before they reach the road.

The Anglo-French supersonic airliner, built by Sud Aviation and the British Aircraft Corporation under a 1962 treaty, flew for the first time from Toulouse. Four Rolls-Royce/Snecma Olympus 593 turbojets drove an ogival delta wing carrying 92 to 128 passengers.

ESTIMATED75% CONFIDENCEThe paper's own header gives the issue and no day: Communications of the ACM, "Volume 13 / Number 6 / June, 1970". A month with no day is estimated at that month's last day.[1]
Ted Codd's paper in Communications of the ACM proposes storing data as relations queried by predicate logic, independent of how it is laid out on disk. It is the founding document of the relational database and of SQL.
CONFIRMED90% CONFIDENCEThe source[1] dates the strike in its opening line — it "struck East Pakistan (present-day Bangladesh) and India's West Bengal on 12 November 1970" — though its own track narrative says the cyclone peaked on 10 November and made landfall "on the following afternoon". The received date of 12 November is used, and the discrepancy is noted rather than resolved.
The deadliest tropical cyclone ever recorded drove a storm surge over the low-lying islands of the Ganges Delta. At least 300,000 died, and the Pakistani government's response helped set off the Bangladesh Liberation War.

ESTIMATED75% CONFIDENCEWikipedia[1] gives the year only - Waters "opened Chez Panisse in 1971 with the film producer Paul Aratow" - so the pin sits on that year's last day.
Alice Waters opened Chez Panisse in 1971 with the film producer Paul Aratow, in a house on Shattuck Avenue, and in doing so more or less founded what came to be called California cuisine: a short menu set by what the farms around the bay had that week rather than by a fixed carte. The block it stands on is now known as the Gourmet Ghetto.
CONFIRMED82% CONFIDENCEThe Office of the Historian states that "Nixon travelled to Communist China February 21–28, 1972, becoming the first U.S. President to visit mainland China while in office", and the Shanghai Communiqué itself records the visit as running "from February 21 to February 28, 1972".[1]
Richard Nixon spent 21 to 28 February 1972 in Beijing, Hangzhou and Shanghai, meeting Mao Zedong on the day he arrived. No sitting US president had set foot in the People's Republic, and the two governments had had no diplomatic relations for 23 years.
