Decades are ten-year periods that help us categorize and understand historical events, cultural shifts, and societal changes. Each decade often has its own unique characteristics, trends, and notable figures, such as the 1960s known for its counterculture movements and the 1980s celebrated for its pop culture and technological advancements. The significance of decades extends beyond mere timekeeping; they serve as a framework for analyzing progress and change in various fields, including music, fashion, and politics. For instance, the 1990s brought about the rise of the internet, fundamentally altering communication and information sharing.
