Kanye West's G.O.O.D. Music collab Cruel Summer dropped on September 18 of this year, slipping in before the end of the season by the thinnest of technicalities, and so close to autumn that we warned the crew against naming any follow-up albums after subsequent seasons. Why give yourself such a narrow time restriction if you don't have to?

Unfortunately, Yeezy failed to heed our solid advice; rumors have floated for months about another G.O.O.D. Music compilation by the name of Cruel Winter. We got our first solid information about the album during a Big Sean radio appearance today, in which we learned three things:

1. Cruel Winter is still happening, and appears to still be called Cruel Winter.

2. Big Sean will be on it.

3. There's still no release date.

Taken together, those first and third points are cause for consternation. (The second point is too, but that's a discussion for another day.) It's already almost December; with no release date specified, the clock is ticking! Are they going to go down to the wire again?

How much time does G.O.O.D. Music have left to release the album before Cruel Winter becomes hopelessly out-of-date? Let's check:

According to the equinoxes: The last day of winter is March 19. That's 16 weeks away. Four months is certainly enough time to put out an album, but deadlines have a way of passing surprisingly quickly for the G.O.O.D. Music crew.

According to the meteorological method of determining seasons: Meteorologists measure winter as the three coldest months of the year; in the northern hemisphere the season ends February 28. Even tighter!

According to the Attic calendar, followed by the Ancient Greeks Kanye is so fascinated by: Winter ends in mid-April in the Attic calendar, giving Kanye a month-long extension on getting Cruel Winter out. (This also lines up roughly with the last unpleasantly cold day of the season, as well.)

According to Groundhog's Day: If Punxsutawney Phil doesn't see his shadow, winter ends on February 2. If he does, winter lasts for six more weeks, ending on March 16. Kanye better hope for sunshine in central PA that day, otherwise he's got less than ten weeks to finish the album.

According to the academic calendar of Chicago State University, which Kanye briefly attended: Winter break at CSU ends on January 13. That gives him barely more than a month!

So, what are the odds this album actually makes it out before the end of winter? Slim, to say the least. Still, though, it doesn't sound like Kanye's camp will consider a title change that might give themselves more breathing room. As Big Sean admitted today, "You can't call it Cruel Spring."
