Noch koroche dnya (Russian: Ночь короче дня, lit.

Night is Shorter Than Day), is the sixth studio album by Russian Heavy metal band Aria.

During the recording of Noch koroche dnya, the band was about to split up, as vocalist Valery Kipelov was going to leave the band alongside Mavrin to start a new project.

Alexey Bulgakov was hired as a replacement vocalist and recorded several songs with Aria.

Songs for the planned Kipelov and Mavrin project were released as the album Smutnoye Vremia in 1997.
