Quick answer
9 AM EST is 2 PM in London when London is on GMT. If the source is New York during daylight saving time, 9 AM EDT is usually 2 PM London during BST as well.
How to use this time conversion
Eastern and London clocks do not always change on the same date, so transition weeks can create temporary surprises. For work calls, write the city and date instead of relying only on EST.
For one-time calls, confirm the exact date before sending the invite. For recurring calls, use the Meeting Time Finder to test whether the time stays inside working hours for everyone.
