A 8h time gap separates Dublin (UTC+1) and Seoul (UTC+9). When you pick up your morning coffee in Dublin, your counterpart in Seoul is already deep into their afternoon. Getting a meeting right means understanding exactly where those working days intersect.
No working-hours overlap means async-first is not optional — it's the architecture. Set up structured daily handoffs: a written summary at end-of-day in each timezone, a shared task board both sides update, and a weekly call at a mutually acceptable off-hours time. The rotation matters: don't let one region always take the 7 AM or the 10 PM slot.
The less obvious scheduling risk is daylight saving time mismatch. Dublin and Seoul may not shift their clocks on the same date. A meeting booked as "10 AM DUB" in January might show up as "11 AM DUB" in a colleague's calendar in March if your calendar app doesn't handle DST transitions correctly. Check the DST note on this page before setting up recurring meetings.
For truly zero-overlap pairs, the most important investment is async infrastructure: a written daily digest each team can read at the start of their day, a shared decision log so nothing critical gets blocked waiting for a live reply, and a clear escalation path for genuine emergencies. With those in place, most distributed teams find they need far fewer live calls than they assumed.
Dublin is UTC+1 and Seoul is UTC+9, a difference of 8h. This gap may shift by 1 hour during DST transitions.
There is no overlap during standard 9–17 hours. Consider a rotating schedule or an early/late meeting. TimeSync's standup planner can find the least-painful slot.
Yes, partially. Dublin observes daylight saving time; Seoul does not. Dublin's clocks change around March 29 and October 25, shifting the gap between the two cities by 1 hour for part of the year.
Dublin and Seoul have no overlap during standard 9 AM–5 PM business hours.
Under standard 9–5 schedules, no. The 8h gap means the two cities' business days do not overlap. Teams that need synchronous collaboration typically shift one side's hours, rotate the inconvenient slot fairly, or rely on async-first workflows with structured handoffs.
