Gershon Galil also attempted to reconcile a 586 date for the fall of Jerusalem with the data for Jeconiah's exile. Like Thiele, he assumed that the years of exile should be measured from Nisan, but for a different reason. Galil hypothesized that Israel’s calendar was one month ahead of that of Babylon because Babylon had inserted an intercalary month and Israel had not yet done so. This would make Adar (the twelfth month) in the Babylonian records correspond to Nisan (the first month) in Judean counting. But this hypothesis, like Thiele's, runs into difficulty with , since the 25th year of captivity would begin in Nisan of 573 and the fall of Jerusalem, 14 years earlier, would be in 587, not the 586 that Galil and Thiele advocate. There is further conflict with the Babylonian data, because the 37th year of captivity, the year in which Jeconiah was released from prison, would be the year starting in Nisan of 561 BCE, not Nisan of 562 BCE as given in the Babylonian Chronicle. Recognizing these conflicts, Galil admits (p. 377) that his date for the fall of Jerusalem (586 BCE) is inconsistent with the precise data given in the Bible and the Babylonian Chronicle.
