The ancient Egyptian pyramids at Giza have never been accurately dated, although we know that they were built approximately around the middle of the third millennium BC. The chronologies of this period have been reconstructed from surviving lists of kings and the lengths of their reigns, but the lists are rare, seldom complete and contain known inconsistencies and errors. As a result, the existing chronologies for that period (the Old Kingdom) can be considered accurate only to about ±100 years… 

A New Astronomically Based Chronological Model for the Egyptian Old Kingdom

A recently discovered inscription on an ancient Egyptian ointment jar mentions the heliacal rising of Sirius. In the time of the early Pharaohs, this specific astronomical event marked the beginning

Radiocarbon-Based Chronology for Dynastic Egypt

TLDR
This work used 211 radiocarbon measurements made on samples from short-lived plants, together with a Bayesian model incorporating historical information on reign lengths, to produce a chronology for dynastic Egypt, which indicates that the New Kingdom started between 1570 and 1544 B.C.E. and the reign of Djoser in the Old Kingdomstarted between 2691 and 2625 B.E.; both cases are earlier than some previous historical estimates.
