Why people convert CET to Oslo time

  • Scheduling a call from CET to Oslo: a 10:00 AM start in CET lands at 11:00 AM in Oslo, so you can confirm the slot without doing the arithmetic yourself.
  • Finding shared working hours: both CET and Oslo are inside the 9-to-5 working day between 9:00 AM and 4:00 PM CET time (10:00 AM–5:00 PM CEST). That is roughly 7 hours of usable overlap.
  • Watching a live event or market open: CET viewers need 10:00 AM in Oslo to catch a 9:00 AM start there, and 11:00 PM if the event is anchored to CET.
  • Always state the zone abbreviation, not just the hour. "3:00 PM CET" is unambiguous; "3 PM" across a +1h gap is not.
  • Block 9:00 AM–4:00 PM CET as the recurring meeting window if you work primarily from CET and need Oslo colleagues present.
  • Oslo: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
