Season of the Emergence

The Season of the Emergence (Egyptian: ) was the second season of the lunar and civil Egyptian calendars. It fell after the Season of the Inundation (Ꜣḫt) and before the Season of the Harvest ().

The pronunciation of the Ancient Egyptian name for the Season of the Emergence is uncertain as the hieroglyphs do not record its vowels. It is conventionally transliterated Peret or Proyet. The name refers to the emergence of the fertile land beside the Nile from its annual flood and to the growth of vegetation and crops over the following season.

It is also known as Winter.

In the lunar calendar, the intercalary month was added as needed to maintain the heliacal rising of Sirius in the fourth month of the season of the Harvest. This meant that the Season of the Emergence usually lasted from January to May. Because the precise timing of the flood varied, the months of "Emergence" no longer precisely reflected the state of the river but the season was usually the time for the planting and growth of Egyptian grain.

In the civil calendar, the lack of leap years into the Ptolemaic and Roman periods meant the season lost about one day every four years and was not stable relative to the solar year or Gregorian calendar.
