K-pop Eras Timeline: How Long Have You Really Been a Fan?
The five K-pop generations on one timeline, with approximate years and era markers from 1st gen to 5th gen. Find where you started and test your era knowledge with a blind test.
K-pop is usually split into five generations, each spanning roughly five to eight years. The group you first fell for places you on that timeline: 2nd gen for the Wonder Girls and Big Bang era, 3rd gen for BTS and TWICE, 4th gen for aespa and Stray Kids, and 5th gen for the newest debuts. Here is the timeline, with a quiz to test where you really started.

Generation boundaries are approximate and fans debate the edges, but the broad ranges below are widely accepted. Use them to find your starting era.

How do I know which K-pop generation I started in?
Think about the first group whose comeback you followed in real time, not one you discovered later. That group's generation is your entry point. Many fans are surprised to learn their favorite is a generation older or newer than they assumed.
Fan fact: the generation you start in tends to shape your taste for years, but most long-term fans end up following groups across two or three generations.
How can I test my K-pop era knowledge?
The blind test lets you filter by generation, so you can play only the era you grew up on or challenge yourself on the others. For a deeper dive into how the generations are defined, read the full generations guide.
