How this service works
Use when scheduling a meeting across time zones. Input: zones (2-10, IANA or KST/PST/CET), date, work_start/work_end (default 09:00-18:00), include_weekends. Output: JSON overlap windows in UTC and every zone's local time, top 3 one-hour slots ranked by distance from each zone's day edges, partial windows when no full overlap, next DST change per zone. Example: ?zones=America/New_York,Europe/London,Asia/Seoul&date=2026-11-03
Output
A JSON object containing: the anchor date and zone, full and partial overlap windows expressed in UTC and every zone's local time, the top 3 ranked one-hour meeting slots (ranked by distance from each zone's day edges), and the next DST offset change for each zone, plus any explanatory notes.
Example use cases
Global product team standup scheduling
“We have team members in New York, London, and Seoul and want to schedule a standing weekly call on 2026-11-03 — can you find the overlap in our working hours (9am to 6pm) and give me the top three one-hour slots that are least disruptive for everyone?”
Cross-continent investor call planning
“I need to set up a call between investors in America/Los_Angeles and America/New_York and a startup in Europe/Berlin on 2026-03-15 — what are the best overlapping windows during normal business hours, and are there any DST changes I should know about?”
Weekend availability check for distributed team
“Our team spans America/Chicago, Asia/Tokyo, and Australia/Sydney — can you check if there's any working-hour overlap on 2026-07-20 if we include weekends, and list the partial windows if there's no full overlap?”
Technical details
Endpoint
GEThttps://1gateway.dev/v1/time/overlap?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to find shared working-hour windows across 2–10 geographically distributed time zones for a specific date, especially when DST transitions are a concern. It is preferable over generic calendar APIs when you need ranked slot suggestions, partial overlap fallbacks, and per-zone DST alerts in a single call without authentication or signup.
Side effects
- Invalid or unrecognized time zone name returns an error
- Fewer than 2 zones provided returns a validation error
- Date format not matching YYYY-MM-DD returns a 400
- No overlap at all between zones returns empty fullOverlap with partial windows only
- More than 10 zones provided is rejected
- work_start time >= work_end time may return empty results or error
