Each Hong Kong hour with the New York time under EST and EDT. −1 marks the previous day in New York.

A fixed UTC+8 against a moving New York

Hong Kong used summer time on and off until 1979 and has kept UTC+8 ever since, as the IANA time zone database records. New York changes twice a year, on the second Sunday in March and the first Sunday in November, under the rules the US Department of Transportation oversees.

That gives two gaps: 13 hours in the US winter and 12 in the US summer. Because each is about half a day, nearly every Hong Kong office hour falls in the New York night or evening.

The evening shift in New York

Hong Kong's financial district opens while New York is having dinner. At 9:30 AM in Hong Kong it is 8:30 PM the evening before in New York in winter, or 9:30 PM in summer. Traders and analysts who follow Asian markets from the US often work an evening shift for that reason.

For calls, the cleanest slots are early morning in New York, which is the Hong Kong evening, or late evening in New York, which is the Hong Kong morning. 8:00 AM in New York is 9:00 PM in Hong Kong in winter and 8:00 PM in summer.

Do

  • State both dates: Mon 8:00 PM EST / Tue 9:00 AM HKT.
  • Shift recurring calls by an hour for one side in March and November.

Avoid

  • Booking a Friday evening in New York for Hong Kong: it is already Saturday morning there.
  • Forgetting Lunar New Year, when Hong Kong offices close for several days.

For mainland China the numbers are the same: see China time to EST. The live Shanghai clock shows UTC+8 now.
