How to Schedule Recurring Meetings Across Daylight-Saving Changes

Decide whose local time should stay fixed before creating the recurring series. A call anchored to 9 AM in New York can appear at a different London hour during clock-change weeks. When the cities change clocks on different dates, one recurring time cannot stay at the same local hour in both places all year.

Choose the schedule's anchor

For a weekly team call, agree whether the meeting stays fixed to the organizer's local time, another office's local time, or a fixed international time.

Use the city whose local schedule should stay fixed, such as “Every Tuesday at 9 AM New York time.” A named zone follows that city's seasonal clock changes; a fixed UTC offset does not.

If both locations insist on the same local hour all year, you may need separate seasonal arrangements or explicit exceptions. One recurring instant cannot always satisfy both requirements.

The weeks when the time gap changes

The United States and the UK use different clock-change schedules. NIST describes the US rules, and GOV.UK publishes UK dates.

London and New York are usually five hours apart, but the gap temporarily becomes four hours while one location has changed and the other has not. A meeting fixed to New York local time therefore appears at a different London hour during that interval.

Check the actual cities and dates involved. Not every US region follows the same daylight-saving practice, and different parts of the world have different seasonal patterns.

Create the recurring event in the intended zone

In Google Calendar on a computer, create the event, open its full options, and set the time zone beside the date and time fields. Then choose the repeat pattern and appropriate end date. Google's time zone guide describes event zones and local display.

In Outlook, use the event's time zone options in the version you are using, then configure recurrence. Microsoft's time zone guidance explains how meeting times are displayed for recipients.

Do not manually enter a different converted hour for every attendee. Send one correctly defined meeting invitation and let each supported calendar display the local time.

Review more than the first occurrence

Inspect a winter date, a summer date, and the weeks around both locations' clock changes. Use time-zone scales in Google Calendar or Outlook to compare the local times.

Ask a colleague in the other location to confirm what they see on those dates. Next Tuesday's time alone will not show you the winter and summer behavior.

Also inspect working hours. A time shift may move a call into a school pickup, lunch break, or the end of another office's day even though the calendar conversion is correct.

Check copying and subscriptions after the source is right

If the original series is correct but a destination copy is not, compare both provider websites on the affected date. Include the changed occurrence and the ordinary dates around it.

For a recurring meeting copied through Avum, edit the organizer's source and inspect the destination selected in its Sync Rule. Compare the affected transition dates in the connected calendar view and on the providers' websites, including any one-off exceptions.

An ICS feed changes only after its publisher updates it and the subscriber fetches it. For urgent changes, check the invitation or official timetable. Diagnose a one-hour event offset before rescheduling a correct original.

Use exceptions for deliberate one-off changes

If the team agrees to change one awkward week, edit that occurrence through the organizer's supported flow and send the update. Do not move the attendee's local copy and assume everyone else receives the change.

Change one occurrence or the series using the organizer's event editor. If you decide to change the long-term anchor, communicate the new pattern before adjusting the broader series.

Keep real invitations separate from generic busy copies. A destination availability block is not the place to negotiate a new meeting time.
