Where American Time Began — Pennsylvania's Clock Legacy

Pennsylvania played a pivotal role in American time standardization. The Pennsylvania Railroad — once the largest corporation in the world — was instrumental in pushing for standard time zones in 1883. Before that, every city set its own local solar time, causing over 300 different local times across the US.

Punxsutawney Phil — the world's most famous groundhog — makes his prediction at 7:25 AM ET on February 2nd every year. This event, held since 1887, is broadcast globally and is one of the few time-specific annual traditions known worldwide.

Philadelphia and Pittsburgh anchor opposite ends of the state — both on ET. Philadelphia is part of the I-95 Northeast Corridor (alongside NYC and DC), while Pittsburgh is a reinvented tech and healthcare hub with Carnegie Mellon and UPMC driving a robotics renaissance.
