Analysis of information sources in references of the Wikipedia article "Book of Haggai" in English language version.
Hag 2:18 describes how the temple's foundations were laid in the second year of Darius, but neither Haggai nor Zechariah 1–8 mentions the completion of the temple. For that reason, many have concluded that these writings must be dated before 515 BCE (Ristau 2016, p. 119).
While most scholars identify Darius referred to in the Books of Haggai, Zechariah, and Ezra as Darius I (522–486 BCE), some take these references to be Darius II (424–405 BCE) (Dequeker 1993; Hallaschka 2010; Becking 2018).
