Setting

Thirteen Reasons Why is set in a contemporary small American town, likely in the early to mid-2000s based on the use of cassette tapes as a key plot device. While the exact location is never specified, it has the feel of a typical suburban community with a high school, diners, and residential neighborhoods that Clay traverses as he listens to Hannah's tapes.

The story unfolds across various locations within this unnamed town that would be familiar to many American teenagers. Key settings include the high school where much of the drama between characters plays out, as well as local hangouts like the diner where Hannah and Marcus have their disastrous date. Clay's journey also takes him to more private spaces like Hannah's bedroom and the hot tub where a critical incident occurs.
