Why people convert CAT to Portugal time
- Scheduling a call from CAT to Portugal: a 10:00 AM start in CAT lands at 9:00 AM in Portugal, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both CAT and Portugal are inside the 9-to-5 working day between 10:00 AM and 5:00 PM CAT time (9:00 AM–4:00 PM WEST). That is roughly 7 hours of usable overlap.
- Watching a live event or market open: CAT viewers need 8:00 AM in Portugal to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to CAT.
- Always state the zone abbreviation, not just the hour. "3:00 PM CAT" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM CAT as the recurring meeting window if you work primarily from CAT and need Portugal colleagues present.
- Portugal: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
