As of 13 August 2026, AI can only partly book a meeting across UK and international time zones.

What to actually do

1. Hand it to a person

   The route this page recommends

   A person who owns the outcome does this end to end, worth it when the failure is dear.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, chat-fluent skill, and roughly 15 minutes until you can act on the result.

   How to actually do it

   1. Open the calendars used by the organiser and required attendees, and confirm that each calendar shows the correct current time zone and working hours.
   2. Gather the meeting purpose, required and optional attendees, duration, acceptable date range, preferred hours and times to avoid.
   3. Paste those details into the prompt, including the organiser's time zone and the meeting platform.
   4. Ask the AI to produce up to three slots with the local date and time for every attendee, and to flag missing information or daylight-saving assumptions.
   5. Compare each proposed slot with the live calendars and the time-zone settings, then select one slot that satisfies the required attendees and constraints.
   6. Paste the selected slot back into the AI and ask it to draft the invitation, then check the title, agenda, duration, platform and every displayed local time.
   7. Create the event in the calendar, add the required attendees and send it only after the final invitation matches the checked slot.

   Prompt

   Help me schedule a meeting across time zones. Use only the details below and do not invent availability, time zones or calendar access.
   
   Meeting purpose: [purpose]
   Required attendees: [names or roles]
   Optional attendees: [names or roles]
   Meeting length: [minutes]
   Earliest acceptable date: [date]
   Latest acceptable date: [date]
   Preferred working hours for each attendee, in their local time: [details]
   Dates or times to avoid: [details]
   Preferred meeting platform: [Teams, Zoom, Google Meet or other]
   Organiser's time zone: [time zone]
   
   First, list any missing information that prevents reliable scheduling. Then identify up to three possible slots, showing the date, time and time zone for every attendee. Account for current daylight-saving rules, and flag any time-zone assumption that I must confirm. Recommend the best slot only after checking all stated constraints. Draft a concise calendar invitation with a clear title, agenda, duration, platform and time shown in each attendee's local time. Do not send or confirm the meeting unless I explicitly approve one slot.
