Making it work for both sides.
A few habits make cross-time-zone meetings easier.
Best slot: 10:00 a.m. New York / 3:00 p.m. London leaves room on both sides. Avoid Friday afternoons in London, which fall on Friday morning in New York.
The same times apply to Toronto, Boston, Miami and the rest of US/Canadian Eastern Time.
What time is it in London when it is 9 a.m. in New York?+
2:00 p.m. for most of the year. During the short gaps in March and late October/early November, when the US has changed its clocks and the UK has not, it is 1:00 p.m.
Why does the difference change to 4 hours?+
The US moves its clocks on the second Sunday in March and the first Sunday in November; the UK moves on the last Sunday in March and October. For about two weeks after each US change, the two are only 4 hours apart.
What is the best time for a call between New York and London?+
Between 9:00 a.m. and noon in New York (2:00–5:00 p.m. in London). 10:00 or 11:00 a.m. New York time is the most comfortable choice for both.
