Yes, the exact date for the establishment of Israel was 1948.
This was revealed by Revelation 11, in one case.
It is tied to 688AD, the starting year of construction for the Dome of abomination.
The date for the second step, 1980, the establishment of the capital, is tied to the date of completion of the Dome of the Rock, 690AD.
Rev. 11:1 And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the (cube shaped: [Rev 21:16]) temple of God, and the altar (within), and them that worship therein.
Rev. 11:2 But the court, (the site covered by the Dome of the Rock), which is without the temple, (330 ft to the north), leave out, and measure it not; for it is given unto the (muslim) Gentiles:
and the holy city, (The Promised Land), shall they tread (from 688 AD) under foot, (688 +1260 = 1948 AD [Dan 12:11-12]), forty and two months, (or, 30X42 = 1260 years, from the building of the Dome of the Rock, that Abomination of Desolation, until 1948 AD, the re-establishment of Israel: [Rev 12:6]).
Rev. 11:3 And I will give power unto my two witnesses, (the Old Testament; [Psa 19:7:The law] and the New Testament; [Psa 19:7: the testimony]), and they shall prophesy: a thousand two hundred and threescore days, (30X42 = 1260 years, from the building of the Dome of the Rock, that Abomination of Desolation: [Dan 12:11], until 1948 AD, the re-establishment of Israel: [Rev 12:6]), clothed in sackcloth (of Scripture).
