Method, example and limitations
Understand the result before using it
Use the planner to translate one proposed meeting instant into local civil times and to identify compromises across working days. It is date-sensitive: a city pair can have one offset in January and another in July because daylight-saving transitions do not occur everywhere or on the same dates.
What the tool does
The first city supplies the local date and time. The browser converts that local value into one UTC instant using its IANA time-zone rules, then formats that same instant in every selected zone. Suggested slots are ranked by how far each participant falls outside the planner’s stated 8:00 am–6:00 pm working window.
Perth meeting on 5 August 2026 at 9:00 am
- Perth is UTC+8, so the meeting instant is 1:00 am UTC.
- Singapore is also 9:00 am; London is 2:00 am during British Summer Time.
- New York is 9:00 pm on 4 August while daylight saving is active.
How to read it: A correct conversion does not make a time considerate. Review the local date as well as the clock time, and rotate inconvenience when no slot fits everyone.
- The device has current time-zone data.
- The selected city represents the participant’s applicable civil-time rules.
- The working-hours score is a planning aid, not an employment-rule assessment.
- Using a fixed UTC offset for a future date.
- Forgetting that another city may be on the previous or next calendar day.
- Treating a city abbreviation such as CST as globally unambiguous.
