Time-dependent density functional theory has become the most widely used tool to investigate excited state properties. However, the selection of an adequate exchange-correlation functional remains a major issue. In this review, the results obtained through recent benchmarks are summarized and several properties considered: vertical and adiabatic transition energies, dipoles, geometries, oscillator strengths, and vibrational signatures. The review concludes with a set of general guidelines for active practitioners.
