| Daylight saving | New York moves to EDT (UTC-4) on the second Sunday of March and back to EST (UTC-5) on the first Sunday of November. |
| Business hours | Offices commonly run 9:00 to 17:00 or 18:00, and the stock exchanges trade 9:30 to 16:00 on weekdays. Banks open around 9:00 to 17:00, and many shops and restaurants open seven days. |

National TV listings, earnings releases and the New York Stock Exchange all work on Eastern Time, so many Americans outside the East still think in ET for business. The opening bell rings at 9:30 and trading ends at 16:00.
New York shares its clock with Boston, Washington, Miami, Atlanta and Toronto. Common errors come from writing EST in summer, when the correct label is EDT. If an invite says EST in July, it almost always means local New York time rather than UTC-5.
India is 9h30 ahead of New York during EDT and 10h30 ahead during EST. That makes the late New York evening the Indian morning, and the early New York morning the Indian evening. Many teams hold an 8:30 New York call that reaches Delhi at 18:00 or 19:00.
London is five hours ahead for most of the year, and Los Angeles three hours behind. Between the second Sunday of March and the last Sunday of March, and again from late October to the first Sunday of November, the New York to London gap is only four hours.
EDT (UTC-4) from the second Sunday of March to the first Sunday of November, and EST (UTC-5) otherwise.
On Sunday 1 November 2026 at 2:00, clocks go back to 1:00 EST.
The 9:30 ET open is 14:30 in London for most of the year and 19:00 or 20:00 in India, depending on the season.
