There’s an enormous amount of chronological information in the Bible, but it is rare for Scripture to date an event by day, month, and year together.
It happens at the completion of major construction projects, when worlds are completed – the world of the tabernacle (Exodus 40:17), the temple (2 Chronicles 3:2), and the second temple (Ezra 6:15). In keeping with this, prophetic oracles concerning construction projects are dated similarly (cf. Ezekiel 1:1; 40:1; Haggai 1:1; Zechariah 1:7).
The Passover is the model, dated not only by day, month, year but by hour.
