San Francisco is a cultural, commercial, and financial hub in Northern California, with a population of over 880,000 (metro area nearly 4.7 million). Famous for its steep rolling hills, eclectic architecture, and stunning waterfront, it is one of the most densely populated major US cities and a global icon.
The city is synonymous with the Golden Gate Bridge, one of the most photographed structures in the world. Other legendary landmarks include Alcatraz Island (the infamous former federal prison), Fisherman's Wharf, Pier 39 with its sea lions, the winding Lombard Street, and the historic cable cars that climb the city's steep streets.
San Francisco is the heart of the global technology industry. The adjacent Silicon Valley (south of the city) is home to Apple, Google, Meta, Netflix, and countless other tech giants. Within the city, major tech companies like Salesforce (whose headquarters dominates the skyline), Uber, Airbnb, Twitter (now X), and Dropbox are based. The city is also a leader in biotechnology, finance, and tourism.
Culturally, San Francisco has always been at the forefront of social change — from the Beat Generation of the 1950s to the Summer of Love in 1967 and the LGBTQ+ rights movement.

Note on DST transitions: The offsets shown above reflect the current live offset, which changes twice a year due to Daylight Saving Time. The US, EU, and other regions change their clocks on different dates, which means the difference between San Francisco and a European city can vary by 1 hour for a short period in spring and autumn. Always verify the exact time difference around DST transition dates for critical scheduling.
