! # From Paul Eggert (2014-01-10):
! # For now, guess that Fiji springs forward the Sunday before the fourth
! # Monday in October, and springs back the penultimate Sunday in January.
! # This is ad hoc, but matches recent practice.

+ # Base the Bougainville entry on the Arawa-Kieta region, which appears to have
+ # the most people even though it was devastated in the Bougainville Civil War.
+ #
+ # Although Shanks gives 1942-03-15 / 1943-11-01 for JST, these dates
+ # are apparently rough guesswork from the starts of military campaigns.
+ # The World War II entries below are instead based on Arawa-Kieta.
+ # The Japanese occupied Kieta in July 1942,
+ # according to the Pacific War Online Encyclopedia
