Why people convert GST to Lisbon time
- Scheduling a call from GST to Lisbon: a 10:00 AM start in GST lands at 7:00 AM in Lisbon, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both GST and Lisbon are inside the 9-to-5 working day between 12:00 PM and 5:00 PM GST time (9:00 AM–2:00 PM WEST). That is roughly 5 hours of usable overlap.
- Coordinating a GST-based team with Lisbon contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM GST" is unambiguous; "3 PM" across a -3h gap is not.
- Block 12:00 PM–5:00 PM GST as the recurring meeting window if you work primarily from GST and need Lisbon colleagues present.
- Lisbon: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
