Stars will be visible tonight after the end of twilight, which for many locations is around 8:15 PM local time on September 15, 2025. After this time, the sky becomes sufficiently dark for stars to be seen clearly. The exact time depends on the location, but generally, stars appear visible soon after sunset and twilight ends. For example, in Washington DC on September 15, 2025, sunset is around 7:17 PM and the end of twilight is around 8:15 PM, so stars will be visible after that time as the sky darkens further.
