Was the destruction of the first Temple in 586 BC or 587 BC?

There is much in scripture concerning the fall of Jerusalem and the destruction of the Temple and of the city walls, and carrying more Jews into captivity. (e.g. 2 Kings 25:1-19; 2 Chron 36:18-19; Jeremiah 39, 52:7-25; Ezekiel 24:1-2, 26:1-2, 30:20-21, 33:21, 40:1). A previous question was not interested in whether it was 586 or 587 but merely sought to compare either 586 or 587 BC with the Watchtower date of 607 BC for the destruction of the Temple. This question asks: Was Jerusalem captured and the Temple destroyed in 586 BC or in 587 BC?
