From the Visit Pittsburgh site, for 4/12’s occasion, “How to Celebrate 412 Day in Pittsburgh”:
We love celebrating Pittsburgh every day, but 412 Day is an extra excuse to honor all things Steel City.
Whether you live in the 412 or outside of it (maybe the 724 or 814?), people far and wide come to Pittsburgh to celebrate 412 Day every April 12th. The city comes alive in fun festivities and Pittsburgh pride
Background 1. The Mysteries of Pittsburgh is a 1988 novel by Michael Chabon.
Background 2, 412 is the phone area code covering the city (now in overlays with some other area codes, especially 878 and 724); it’s associated with Pittsburgh the way 212 is with Manhattan, 215 with Philadelphia, and 415 with San Francisco.
Background 3. From Wikipedia:
The economy of Pittsburgh … is diversified, focused on services, medicine, higher education, tourism, banking, corporate headquarters and high technology. Once the center of the American steel industry, and still known as “The Steel City”, today the city of Pittsburgh has no steel mills within its limits, though Pittsburgh-based companies such as US Steel, Ampco Pittsburgh and Allegheny Technologies own several working mills in the Pittsburgh metropolitan area.
Background 4. The physical setting: the three rivers:
Where the Allegheny (in the northeast) and the Monongahela (in the southeast) meet to form the Ohio, which flows west into Ohio (the Dustin McGrew Photography aerial photo has been rotated to give a more dramatic view)
The Ohio then flows southwest along the border of West Virginia with Ohio, then along the border of Kentucky with, in order, Ohio, Indiana, and Illinois, emptying into the Mississippi at Cairo IL.
The pleasures of Pittsburgh. A sampling of my favorite things. But it’s a small core city (about 303,000 people) in a big metro area (about 2.43 million), much like San Francisco in this respect. With a high-intensity core surrounded by a wider area in which many things are available.
The terrain. Pittsburgh is a city of steep hillsides — some streets that have steps for sidewalks — and an enormous number of bridges (446, by one count), some over water, but many over valleys. Views, neighborhoods, strenuous walking.
Academia. Notably the University of Pittsburgh (Opal Armstrong Zwicky is a graduate of Pitt) and Carnegie-Mellon University (more tech-oriented: created by the union of the Carnegie Institute of Technology and the Mellon Institute of Industrial Research).
Museums. Especially the Carnegie Museums of Art and of Natural History, the Carnegie Science Center, and the Andy Warhol Museum.
Plants. In the Phipps Conservatory and Botanical Gardens.
Your own list would no doubt tilt in other directions.

And on a truly personal note: Pittsburgh is the home of several old friends, notably Ann Burlingham and Jason Parker-Burlingham (who appear often as characters on this blog)
