"'Six Days" is a song by American trip-hop artist DJ Shadow, from his second album, The Private Press.

The song's music video was directed by Hong Kong director Wong Kar-wai.

Shadow approached Wong Kar-wai, one of his favorite directors, in an attempt to create a music video unlike his previous ones.

The idea was to make a short film revolving around the song's hook line: "Tomorrow never comes until it's too late..." The plot is centered on a man (Chang) who, upon discovering his girlfriend (Graham) has cheated on him, tries to destroy all traces of their relationship, eventually realizing that this is futile, as what has happened cannot be undone.

It contains numerous instances of the number 426, a reference [citation needed] to Wong Kar-wai's then-upcoming film 2046.
