Best Meeting Time: Sydney to Dublin
🕐 Live Timezone Overlap: Sydney & Dublin
Sydney and Dublin sit 9 hours apart, with Dublin behind. That gap is wide enough that the standard 9am–6pm working day in each city produces zero overlap: when Sydney's team clocks off at 6pm, it is only 9am in Dublin. Every cross-city meeting therefore requires at least one side to attend outside normal hours. Planning ahead, communicating expectations clearly, and rotating the burden fairly between teams are the practical starting points for anyone scheduling regularly across these two cities.
Time Difference: Sydney and Dublin
Dublin is currently 9 hours behind Sydney. The live offsets are Sydney UTC+10 and Dublin UTC+1. Sydney observes daylight saving and Dublin also observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
Sydney currently runs at UTC+10, its standard offset. Dublin is currently on Irish Standard Time at UTC+1, one hour ahead of its winter baseline of UTC+0. Both cities observe DST, but their clocks shift at different times of year: Sydney follows southern-hemisphere DST from October to April, while Dublin follows the European schedule from March to October. When Sydney moves to AEDT (UTC+11) in October, the gap widens from 9 hours to 10 hours. When Dublin moves to IST (UTC+1) in March, the gap narrows back.
Best Times to Meet
There is no in-hours overlap between Sydney and Dublin. A 6pm finish in Sydney is 9am in Dublin, leaving no room within a standard 9am–6pm working day on either side. The least disruptive option for Sydney is a call placed as late as possible, around 5pm to 6pm local time. For Dublin, that same call lands at 8am to 9am, before normal working hours begin. Dublin participants effectively need to start early, and Sydney participants should treat late afternoon as their dedicated window for this pairing.

Tips for Scheduling Across Sydney and Dublin
- Rotate early-morning starts between Dublin and Sydney teams so one side does not always carry the inconvenience.
- Sydney's 5pm to 6pm slot is the closest you can get to business hours for a Dublin 8am to 9am call.
- Avoid scheduling Sydney-Dublin calls in late December and early January: Sydney offices run on skeleton staff through the summer holiday period.
- Dublin's St Patrick's Day (17 March) is a national holiday: remove it from any recurring meeting series in advance.
- When Sydney shifts to AEDT in October, update your calendar tool immediately as the gap widens to 10 hours from the usual 9.
Public Holidays and Working Weeks
Both cities follow a Monday to Friday working week. Key holidays to watch: Sydney observes Australia Day on 26 January and ANZAC Day on 25 April, and offices run on skeleton staff from Christmas through to Australia Day during the summer holiday season. Dublin closes for St Patrick's Day on 17 March, the May Bank Holiday, and Christmas. Any recurring meeting series crossing Sydney and Dublin should be checked against both holiday calendars to avoid scheduling into silent offices on either side.
