Semibreve vs. Whole Note
This is a regional terminology difference in music notation, not a correctness dispute. The written value is the same; actual performed duration still depends on meter and tempo.
“Semibreve” is the standard UK music term and “whole note” the standard US term for the same written note value.

Quick tests
Decision test
Are you choosing the regional name for the same written note value?
If yes: Use “semibreve” in UK terminology and “whole note” in US terminology.
If no: If you are discussing how long it lasts in performance, describe the musical context rather than treating either label as a fixed number of seconds.
Caveat: Treat the pair as regional equivalents for the notation value; do not turn the regional naming difference into a rule about performance duration.
Examples
The exercise begins with a semibreve.
UK music terminology uses “semibreve” for this note value.
The measure opens with a whole note.
US music terminology uses “whole note” for the same written value.
The conductor changed the tempo, so the whole note lasted longer in seconds.
The notation value remains the same while performed duration changes with tempo.
