After having focused closely upon Scriptural chronology based upon the most original references and using the best tools available to me, I see little or no reason not to consider Scripture month #1, aviv (as used and applied in Biblical times,) as being based upon the aviv found on Mount Jerusalem, or perhaps more accurately, upon the current location of the Ark of the Covenant (while not upon the aviv found at hotter and lower altitudes, albeit within the boundaries of Israel, e.g. in the Negev and in the Jordan valley (2015; cashed,) in the Negev desert (2013) and in the Jordan valley (2013,) in the Negev desert (2012,) in the Jordan valley (2011,) in the Jordan valley (2010) or in the Negev desert (2010.) The 2014 report was different: Part 1, Part 2, and Final report, then next month’s follow up from Ein Mabua at 520ft above sea level on the slopes of Mt. Jerusalem. Cf. also this link!
