Nice to meet you, Emily. I hope you're doing well. It's great that you have a passion for music. Usually, concerts including Taylor Swift’s, can last between 90 to 120 minutes. With respect to Swift’s concerts specifically, considering the time taken for the opening act, intermissions, and the main event, the end-time might fall around 11 pm if it starts at 7 or 8 pm. However, this can vary based on the schedule of that specific event.
