Working between Dublin and Shanghai
The difference between Dublin and Shanghai is not really a number, it's a daily rhythm. Shanghai is 8 hours ahead of Dublin on the clock today, but the lived version is that Shanghai is wrapping up the working day while Dublin is still in the morning, and the overlap people actually use is narrow. That gap, more than the raw offset, is what teams have to design around.
In Dublin, the working day picks up earliest in the financial districts- Dublin's downtown core wakes early and breaks for lunch at the usual hour. The mood in Shanghai is its own story: Shanghai settles into the evening at the usual hour, with the local commuter pattern setting the pace. If you are scheduling between the two, the heatmap above marks the rows where both patterns line up.
Daylight saving is the other thing to keep an eye on. Ireland shifts the clock on the last Sunday of March and October; China either follows its region's DST pattern or stays put all year. When the two changes are weeks apart, the offset between Dublin and Shanghai is one hour off the usual for that stretch, a cliff that catches recurring calendar invites unless your calendar app rebases them automatically. Pin the meeting to a city, not an offset, and the tool handles the rest.
For travellers, the 11h 60m flight is the short version of the story. The longer one is jet lag: roughly one day of adjustment per timezone crossed, which means a trip across the 8-hour gap costs about 8 groggy days on each side. Pilots and cabin crew swear by morning sunlight and an early walk; whatever your routine, the wall-clock numbers above are the source of truth for your first morning in the new city.
