You mean the 4th War? It lasted only a few days. Maybe 2-4 days. Not more than that, since I remember night falling for the first time when Kakshi's squad was engaged with the Seven Swordsmen of the Mist; Gaara and Onoki's squad were approaching the 4 revived Kiage; and when Obito stole the sealing vessel in which Kinkaku and Ginkaku were sealed. The next day the four Edo Tensei Kages were defeated, then Madara was revived and by night time of the same day the Juubi had also been revived. Kaguya was probably defeated in the same night or the next morning. At least that's the impression that I got from the manga.
