The Nobel Peace Prize is intended to be awarded once a year , usually every year, but there have been years when it was not awarded at all (for example during World War II).

How often it’s awarded

  • The Nobel Peace Prize is designed as an annual prize, decided and announced in early October and presented on 10 December each year in Oslo.
  • However, the Norwegian Nobel Committee can decide not to award it in a given year if it judges that no candidate meets Alfred Nobel’s criteria, which is why some years in the historical list show “not awarded.”

Exceptions in history

  • Since the first Peace Prize in 1901, there have been multiple years when it was skipped, notably during the World War II years (1940–1943), when no Peace Prize was given.
  • Overall, this means the prize is functionally annual in intention and practice, but not absolutely guaranteed every single year.

TL;DR: They award the Nobel Peace Prize once a year in principle, but in some years (especially during major conflicts like World War II) it has not been awarded.
