- Finding shared working hours: both Oslo and New York are inside the 9-to-5 working day between 3:00 PM and 5:00 PM CEST time (9:00 AM–11:00 AM EDT). That is roughly 2 hours of usable overlap.

- Oslo: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -6h gap.
