London time: planning calls across the Atlantic

A London scheduling guide for overseas teams, visitors and recurring meetings.

The local clock and calendar zone

Start with the current time in London. The calendar identifier is Europe/London. It represents the location’s time rules, while the clock page shows the current situation. For a later appointment, check the event date rather than treating today’s offset as permanent.

Keep the London meeting anchored to London

A London appointment should follow the organizer’s intended local time, rather than a fixed offset copied from an old email. For a weekly team call, choose Europe/London in the invitation. If colleagues join from New York, inspect a meeting in March and another in late October: the countries do not always change clocks on the same weekend. A familiar five-hour difference is not a reliable year-round instruction.

Travel days need a separate check

For an arrival followed by a meeting, record the landing time and meeting time as separate London appointments. Leave the actual transfer duration to the airport and transport operator; a clock conversion cannot predict it. If your phone still displays your departure city, compare its zone setting with the London clock before setting an alarm. Our travel guide explains why subtracting two local clock readings does not necessarily give journey duration.

Before you send the invitation

Check the full date, starting time, ending time and organizer’s city. Open the saved event once to confirm its displayed zone. For the underlying distinction between a zone and a numeric offset, read UTC and local time. Keep your calendar software updated and confirm any important schedule change with the organizer.
