Timezone facts
Greenwich in context
Greenwich sits on the Long Island Sound coast in southwestern Connecticut, around 50 kilometres northeast of Manhattan and connected to it by frequent Metro-North commuter rail. The town proper holds around 64,000 residents across an unusually large municipal area of 175 square kilometres, with the wealthier shoreline backcountry and more compact downtown clearly distinguished. It serves as the principal residential anchor of the Connecticut Gold Coast.
Timezone history of Greenwich
This Greenwich shares neither its name nor its longitude with the Royal Observatory that defines Greenwich Mean Time: the Connecticut town sits at around 73 degrees west, almost five hours behind the prime meridian. It uses Eastern Time and observes the federal DST schedule, the same offset as Manhattan and the rest of the New York City metropolitan area to which it functionally belongs as a commuter satellite.
Working hours in Greenwich
Greenwich is the principal residential and operating base for a substantial share of the US hedge-fund industry. The town hosts dozens of fund headquarters and family offices, with working hours that overlap with both London and Asian market opens: pre-dawn starts before 06:00 are common, and trading floor staffing typically runs through to the New York close at 16:00. The conventional 09:00-to-17:00 office day applies in town-government and retail employment outside the fund corridor.
