Why people convert Taiwan to GST time
- Scheduling a call from Taiwan to GST: a 10:00 AM start in Taiwan lands at 6:00 AM in GST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Taiwan and GST are inside the 9-to-5 working day between 1:00 PM and 5:00 PM CST time (9:00 AM–1:00 PM GST). That is roughly 4 hours of usable overlap.
- Watching a live event or market open: Taiwan viewers need 5:00 AM in GST to catch a 9:00 AM start there, and 4:00 AM if the event is anchored to Taiwan.
- Always state the zone abbreviation, not just the hour. "3:00 PM CST" is unambiguous; "3 PM" across a -4h gap is not.
- Block 1:00 PM–5:00 PM CST as the recurring meeting window if you work primarily from Taiwan and need GST colleagues present.
