Understanding the Sydney – Dublin Time Difference
Sydney runs on Australia/Sydney, currently AEDT (UTC+11:00). Dublin runs on Europe/Dublin, currently IST (UTC+1:00). The gap of 10 hours is simply the distance between those two offsets.
Both cities observe Daylight Saving Time, but they don't switch on the same date — so for a few weeks each year the gap between them is different again. The next shift is on Sunday, October 25, 2026, when Dublin adjusts its clocks and the difference becomes 11 hours. Anything scheduled across that date needs checking again.
