The majority of Egyptologists agree on the outline and many details of the chronology of Ancient Egypt. This scholarly consensus is known as the Conventional Egyptian chronology, which places the beginning of the Old Kingdom in the 27th century BC, the beginning of the Middle Kingdom in the 21st century BC and the beginning of the New Kingdom in the mid 16th century BC. Despite this consensus, disagreements remain within the scholarly community, resulting in variant chronologies diverging by about 300 years for the Early Dynastic Period, up to 30 years in the New Kingdom, and a few years in the Late Period. In addition, there are a number of "alternative chronologies" outside scholarly consensus, such as the "New Chronology" proposed in the 1990s, which lowers New Kingdom dates by as much as 350 years, or the "Glasgow Chronology" (proposed 1978–1982), which lowers New Kingdom dates by as much as 500 years.

Forming the backbone of Egyptian chronology are the regnal years as recorded in Ancient Egyptian king lists. Surviving king lists are either comprehensive but have significant gaps in their text (for example, the Turin King List), or are textually complete but fail to provide a complete list of rulers (for example, the Abydos King List and the Palermo Stone), even for a short period of Egyptian history. The situation is further complicated by occasional conflicting information on the same regnal period from different versions of the same text; thus, the Egyptian historian Manetho's history of Egypt is only known by epitomes and references to it made by subsequent writers, such as Eusebius and Sextus Julius Africanus, and the dates for the same pharaoh often vary substantially depending on the intermediate source. Regnal periods have to be pieced together from inscriptions, which will often give a date in the form of the regnal year of the ruling pharaoh. Yet this only provides a minimum length of that reign and may or may not include any coregencies with a predecessor or successor. In addition, some Egyptian dynasties probably overlapped, with different pharaohs ruling in different regions at the same time, rather than serially. Not knowing whether monarchies were simultaneous or sequential results in widely differing chronological interpretations. Where the total number of regnal years for a given ruler is not known, Egyptologists have identified two indicators to deduce that total number: for the Old Kingdom, the number of cattle censuses; and for later periods, the celebration of a Sed festival. A number of Old Kingdom inscriptions allude to a periodic census of cattle, which experts at first believed took place every second year; thus records of as many as 24 cattle censuses indicate Sneferu had reigned 48 years. However, further research has shown that these censuses were sometimes taken in consecutive years, or after two or more years had passed. The Sed festival was usually celebrated on the thirtieth anniversary of a pharaoh's ascension, and thus rulers who recorded celebrating one could be assumed to have ruled at least 30 years. However, once again, this may not have been standard practice in all cases. In the early days of Egyptology, the compilation of regnal periods was also hampered by a profound biblical bias on the part of Egyptologists. This was most pervasive before the mid 19th century, when Manetho's figures were recognized as conflicting with biblical chronology, based on Old Testament references to Egypt (see Pharaohs in the Bible). In the 20th century, such biblical bias has mostly been confined to alternative chronologies outside the scholarly mainstream.

A useful way to work around these gaps in knowledge is to find chronological synchronisms, which can lead to a precise date. Over the past decades, a number of these have been found, although they are of varying degrees of usefulness and reliability. Seriation, i. e. archeological sequences. This does not fix a person or event to a specific year, but establishing a sequence of events can provide indirect evidence to provide or support a precise date. For example, some inscribed stone vessels of the rulers of the first two dynasties were collected and deposited in storage galleries beneath and sealed off when the Step Pyramid of Djoser, a Pharaoh of the Third Dynasty, was built. Another example are blocks from the Old Kingdom bearing the names of several kings, which were reused in the construction of Middle Kingdom pyramid temples at Lisht in the structures of Amenemhat I. Likewise, the third pylon at Karnak, built by Amenhotep III contained as "fill" material from the kiosk of Sesostris I, along with various stelae of the Second Intermediate Period and the Eighteenth Dynasty of the New Kingdom. Synchronisms with other chronologies, the most important of these being with the Assyrian and Babylonian chronologies, but synchronisms with the Hittites, ancient Palestine, and in the final period with ancient Greece, are also used. The earliest such synchronism is in the 18th century BC where a stela of the governor of Byblos Yantinu indicates that pharaoh Neferhotep I was contemporary with kings Zimri Lim of Mari and Hammurabi of Babylon. Other early synchronisms date to the 15th century BC, during the Amarna Period, when we have a considerable quantity of diplomatic correspondence between the Egyptian Kings Amenhotep III and Akhenaten (or possibly Smenkhkare), and various Near Eastern monarchs. (See Chronology of the Ancient Near East.) For the Third Intermediate Period, Shoshenq I has been ascribed a date relative to Rehoboam and the Eponym dating system by Kenneth Kitchen, based on biblical passages about Shishak's campaign. Shoshenq I's absolute date was calculated based on Edwin R. Thiele's theory. Synchronisms with memorials of Apis bull interments. These begin as early as the reign of Amenhotep III and continue into Ptolemaic times, but there is a significant gap in the record between Ramesses XI and the 23rd year of Osorkon II. The poor documentation of these finds in the Serapeum of Saqqara also compounds the difficulties in using these records. Astronomical synchronisms. The best known of these is the Sothic cycle, and careful study of this led Richard A. Parker to argue that the dates of the Twelfth dynasty could be fixed with absolute precision. More recent research has eroded this confidence, questioning many of the assumptions used with the Sothic Cycle, and as a result experts have moved away from relying on this Cycle. For example, Donald B. Redford, in attempting to fix the date of the end of the Eighteenth dynasty, almost completely ignores the Sothic evidence, relying on synchronicities between Egypt and Assyria (by way of the Hittites), and help from astronomical observations. Radiocarbon dating. This is useful especially for the Early Dynastic period, where Egyptological consensus has only been possible within a range of about three or four centuries. Radiocarbon dating is roughly consistent with Shaw's conventional chronology. A 2013 study found a First Dynasty start in the 32nd or 31st century, compatible with scholarly opinions placing it in between the 34th and 30th centuries. The Thera eruption. This is a famous conundrum not just in Egyptian but also in Aegean (Minoan) chronology, as the radiocarbon date for the eruption, between 1627 and 1600 BC (p=5%), is off by a full century compared to the date traditionally accepted in archaeology of c. 1500 BC. Since 2012, there have been suggestions that the solution lies in adjusting both dates towards a "compromise" date in the mid 16th century BC, but as of 2023 the problem has not been satisfactorily resolved. Dendrochronology. There have been occasional opportunities to use dendrochronology to support Egyptian chronology, mostly for the New Kingdom period, e. g. the Uluburun shipwreck. Combined use of dendrochronology and radiocarbon dating allowed identification of tree rings even back to the Middle Kingdom period, as in the coffin of Ipi ha ishutef (dated 2073±9 BC) or the funerary boat of Senusret III (dated 1887±11 BC; conventional reign date 1878 BC–1839 BC).
