Why people convert Ireland to Taipei time
- Scheduling a call from Ireland to Taipei: a 10:00 AM start in Ireland lands at 5:00 PM in Taipei, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Ireland and Taipei are inside the 9-to-5 working day between 9:00 AM and 10:00 AM IST time (4:00 PM–5:00 PM CST). That is roughly 1 hours of usable overlap.
- Watching a live event or market open: Ireland viewers need 4:00 PM in Taipei to catch a 9:00 AM start there, and 5:00 PM if the event is anchored to Ireland.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +7h gap is not.
- Block 9:00 AM–10:00 AM IST as the recurring meeting window if you work primarily from Ireland and need Taipei colleagues present.
- Ireland: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the +7h gap.
About GMT (Greenwich Mean Time)

GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.

China does not observe daylight saving time. CST is shared with Hong Kong (HKT), Macau, Taiwan, Singapore, Malaysia, and the Philippines, making UTC+08:00 one of the most used offsets in the world.
