Why people convert ICT to Lisbon time
- Scheduling a call from ICT to Lisbon: a 10:00 AM start in ICT lands at 4:00 AM in Lisbon, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both ICT and Lisbon are inside the 9-to-5 working day between 3:00 PM and 5:00 PM ICT time (9:00 AM–11:00 AM WEST). That is roughly 2 hours of usable overlap.
- Watching a live event or market open: ICT viewers need 3:00 AM in Lisbon to catch a 9:00 AM start there, and 6:00 AM if the event is anchored to ICT.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -6h gap is not.
- Block 3:00 PM–5:00 PM ICT as the recurring meeting window if you work primarily from ICT 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.
