Something that happens once a century.
Rumpelstiltskin slept for 100 years before being awakened by the princess in some versions of the story.
Something that happens every 100 years is called a centennial. It marks a significant milestone or anniversary reaching the 100-year mark.
The expectation is that we sleep about 20% less then 100 years ago. This is due to the imitation light in houses that influences our melatonin levels. 100 years ago we did not have a light source such as a television that bombards the brain with signals and light. Research has shown that watching television before going to bed can influence the sleep hormone melatonin drasticly. See the related link.
A centennial happens every 100 years on that specific day every 100 years. It's the 100th anniversary of something.
