Time Zone Planning Tips
- • Confirm the location and date before comparing times because daylight-saving rules can change the offset.
- • Share the exact date with meeting participants rather than relying only on a clock time.
- • For international meetings, check both the organizer's and attendee's local times before sending an invitation.
