And thou dost know, and dost consider wisely, from the going forth of the word to restore and to build Jerusalem till Messiah the Leader is seven weeks, and sixty and two weeks: the broad place hath been built again, and the rampart, even in the distress of the times.26
And after the sixty and two weeks, cut off is Messiah, and the city and the holy place are not his, the Leader who hath come doth destroy the people; and its end is with a flood, and till the end is war, determined are desolations.27
And he hath strengthened a covenant with many--one week, and in the midst of the week he causeth sacrifice and present to cease, and by the wing of abominations he is making desolate, even till the consummation, and that which is determined is poured on the desolate one.'

That event is dated on the sabbath year 457BC. 1st of the 1st month is 1 Tishri. (Jewish new year, Rosh Hashana, Feast of Trumpets)
Jesus was born on 1 Tishri
457BC + 483 = 27AD (no year 0)
457BC = Decree of Ezra
483 = 69 weeks = 69x7=483 years
Jesus was baptised in autumn of the sabbath year 27AD. I think on His birthday 1 Tishri
Nothing visible was build in 27AD.
The only thing that happened was the Spirit decending from the sky as a dove.
Could that be New Jerusalem?
