The Egyptian Calendar
Introduction and History of the Calendar
About 5000 years ago, the Egyptian kingdom had established along the river Nile. It existed for nearly 3000 years with some interruptions. Circumstances were favourable for the development of the Egyptian civilisation. Every year the river Nile brought fertile mud onto the fields ensuring rich harvests. Quite early Egyptian astronomers discovered the fact, that the flood of the Nile and the first visibility of the star Sirius on the morning sky, called heliacal rising, fell close together. It seems likely that the beginning of the Egyptian calendar year corresponded to a heliacal rising at the time the calendar was established. But, with the calendar year having invariably 365 days, the calendar shifted one day every four years with respect to the seasons. Thus, within 1460 Julian years (of 365.25 days each) 1461 Egyptian years elapsed. This period is called the Sothis Period (1). After a Sothis Period the calendar was in line with nature again.
There is no evidence of when the Egyptian calendar was established. The dates of three heliacal risings, during the reign of Thutmosis III., Amenophis I., and Sesostris III. (2), have come to us. The Roman historian Censorinus wrote that the heliacal rising fell on Egyptian New Year in 139 CE. If the heliacal rising of Sirius and the beginning of the year really corresponded at the time the calendar was introduced, one could reckon (3) the years 1322 BCE, 2782 BCE, or even 4242 BCE. Of course one cannot conclude the introduction of the Egyptian calendar has taken place in the 5th millenium BC from this reckoning alone.
It seems very unlikely that the shift of the calendar through the seasons was not recognized by ancient Egyptian astronomers. Nevertheless, no documents of any serious attempt to correct the calendar have been found yet that are older than the Canopus decree of king Ptolemy III. Euergetes (r. 246 BCE-222 BCE). By this decree, in 238 BCE, Ptolemy ordered an additional day to be added to every fourth year. But in practice the calendar remained unchanged. Only in 30 BCE, Caesar's successor Augustus reformed the Egyptian calendar.
The reform added a leap day to every fourth year, making the year of the Egyptian calendar as long as that of the Julian calendar. Thus, the beginning of the Egyptian year always fell on 29 August except in years preceding a Julian leap year, when the Egyptian year began on 30 August. The shift of one day was then corrected on 29 February the following Julian (leap) year. To distinguish this reformed Egyptian calendar from the original one, the former is sometimes called Alexandrinian calendar.
Unfortunately, the ancient Egyptians had no consecutive counting of the years. They instead wrote the number of the counting of the cattle that took place every other year. A year could be specified, for example, by writing "year of the 3rd counting [in king ...'s reign]", or in a shorter manner, used later, "year of the 3rd time". From the 11th dynasty (about 2100 BCE) the regnal year was written. The beginning of a regnal year was 1 Thot (see below) of the year in which the king came to power. Year one of a king who began his reign on the 3rd additional day would have 3 days only. Beginning with the 18th dynasty (about 1540 BCE) the regnal years were begun on the actual day on which the king came to power. This style was used until the 26th dynasty (about 660 BCE), when the former method came into use again.
Internal Structure
The year was divided into three seasons of four months each. Every month consisted of 30 days. At the end of the year, five additional days were added. Thus a year had 365 days. A date was given as "16th day of the 2nd month of the Inundation", for example. Furthermore, the months were given names, too.
The seasons and months are compiled in the following table.
Season Month
Ache
(Inundation) Thot
Phaophi
Athyr
Choiak
Prôje
(Winter) Tybi
Mechir
Phamenoth
Pharmuthi
Shômû
(Summer) Pachon
Payni
Epiphi
Mesori
Interestingly the Egyptian months seem to have been disconnected from the moon's phases in a quite early stage of the development of the calendar. Thus, complicated mechanisms to keep the months in alignment to the moon were unnecessary which made possible an easy and clear internal structure.

The Ancient Egyptians had two types of calenders.A papyrus that dates from the time of Ramesses II (1290-1224BC). Known as The Cairo Calender.
This was a calender of lucky and unlucky days of the year.The good or bad fortune of a day was determined by past events connected to that date, concerning Gods,omens,battles,or prophesies related tothat time period.
People born on unlucky days were thought doomed to a bad ending.In the case of royal princes,those on who the fate of Egypt depended. Birth dates were critical.If an heir was born on an bad day. The Seven Hathors would arrive and substitute the child for one born on a lucky day. In that way calamities were thought to be avoided.
This calender was used by the literate or upper class Egyptians much like people today consult a horascope.
The other type of calender was of annual designation and dates as far back as predynastic times.This lunar calender was designed for agricultural needs but evolved over the centuaries.
The primary calender had 12 months of 30 days
Its inaccuracy was evident from the beginning.
The lunar cycles and the rotation of the earth around the sun did not coincide.
The Egyptians found that festivals were being celebrated out of season.
It was revised by adding 5 days at the end of each year called Epagomenal days.This provided stability for calculations.
The year contained 3 seasons of 4 months.Akhet was the first.The season of innundation,it began at the end of our August.Next was Peret,the time the land emerged from the floodwaters of the Nile.Then came Shemu,the time of harvest.
The rising of a star called Sopdu or Sopdet by the Egyptians and known to us as the Dogstar or Sirius, started each year on the revised calender.
The arrival of Sopdet at a given time was due to its rising just above the horizen at dawn.At just about the same time of year as Akhet began.
It is interesting that they never stopped using the old calender from predynastic times. But used it along side the revised one.
Something so reverred by thier ancestors could not just be disposed of.
The Tomb of Sety 1 in The Valley of the Kings contains a magnificent vaulted ceiling that deals with astronomical subjects,many are obscure in their meaning.
A hippopotamus and a crocodile near the centre are northern constellations visible in the Egyptian sky.
Photos of this ceiling should be available on the net.
Do a Google for Sety 1 tomb, astonomical ceiling.
It is on of the most beautiful and popular "must sees" in the Valley.
At present it is closed for restoration.
This is about as near as you will get to a picture of an Ancient Egyptian calender. Thier calenders were information from written papyrus and consisted of written information and little pictorial depiction with the exception of a aspect of the moon.
