**a Decade Of Glam:** See How Dolly Parton's Hair Has Stayed Iconic The Evolution Parton A Journey Through Glamour

Decade的概念：從曆法的單位上來看，“decade”是曆法在十年的一個單位，同樣的還有lustrum （5 年），century （100年），millennium（1000年）. In the past decade的同義字'in the past decade' means that it happened at some point within the last ten years.

I guess the only minute difference would be how we use them. 'over the past decade' means that it happened repeatedly, more than once, or. In a decade = in 10 years time this has no specific date.
