Sidereal Calendar (Previous Years)


Calendars from previous years. Still valuable for the art and quotes contained within. The Sidereal Calendar is humanity’s oldest and most astronomically correct calendar.



This calendar is an essential guide for the M’TAM spiritual initiate because it includes the traditional Kemetic Holy Days and the appropriate days to perform spiritual activities and to make offerings to Ancestors and the Divine World. The Sidereal Calendar is based on 3 cycles: The seasonal year of 365/366 days. The medium year of 1461 day (4 seasonal years). The great year of 1461 years. It was used during the times of the Pharaohs and it successfully links individual to his or her heritage an culture by revealing divisions of time accurately. The Sidereal Calendar features the original names of months and days of the week, as well as the original traditional Holy Days, not political “holidays.”

Astronomical Basis

Every 1461 years, the Earth, the Sun and the Sirius Star align. This event, known as the heliacal rising, causes a huge energetic impact on Earth and its inhabitants. Throughout history, this period has coincided with catastrophic events. The Sidereal Calendar was created to chart this cycle. We are currently in the 412th year since the last heliacal rising. This 1461 year cycle is known as a Great Year or a Neter (God) Year.

The cycle of the Sirius Star (known in Kemet as Septet) also influences the seasonal cycles of the Earth. The Kemetic New Year (September 11th) coincides with the time of year when Septet rises at the same time, or close to the same time as the Sun. This time of year also marks the rainy season in the tropical regions, as well as hurricane season.

The Great year of 1461 years can be divided into 365 cycles of 1461 days. The 1461 day cycle can be divided into 3 years of 365 days and 1 year of 366 days. The 1461 day cycle is known as a real year because it is a complete cycle, whereas each 365 or 366 day cycle is known as a seasonal year or a farmer’s year. .

The cycle of the Septet Star also influences the seasonal cycles of the Earth. The Kemetic New Year (September 11th) coincides with the time of year when Septet rises alongside the Sun. This time of year also marks the beginning of the rainy seasons in tropical regions and is considered the pinnacle of hurricane season.

The seasonal year is divided into 13 months: 12 months of 30 days and 1 month of 5 days. Each 30 day month is divided into 10 day periods known as metheru (pronounced “met-heru’). One month of 5 days comes as the 13th month and completes the end of the seasonal cycle. At the end of the 4th consecutive seasonal cycle, a 6th day is added to the 13th month. This day, known as World Renewal Day, is added to keep the calendar in astronomical alignment with the Septet cycle. This is where the modern idea of the leap year comes from.

Spiritual Applications

The Sidereal calendar is also the basis for Kemetic spiritual activities, being the reference for when the Holy Days are and when offerings to the Divine and Ancestral Worlds are to be made.

Each month of the calendar is governed by one of the Kemetic Deities. The characteristics of each Deity will influence the personality of each person born in their respective months. This is the origin of the modern zodiac. The calendar provides a description and depiction of the Deities of each month. Also included are the animals sacred to to each Deity. It is forbidden to consume or kill animals sacred to the Deity governing the month of one’s birth.

The daily spiritual activities of the Kemetic Initiate are known as the zemzem. This is a time of energetic alignment with the Divine World and communion with one’s ancestors. The appropriate days for performing the zemzem and refraining from performing the zemzem are detailed in the calendar.

Each month is divided into periods of 10 days known as metheru (pronounced “met-heru”). Each metheru includes 6 days for performing the zemzem, 2 days of rest where zemzem is not performed, one Ancestral Day where offerings are made to one’s ancestors and one Divine Holy Day where offerings are made to the Divine World. These details are also included in the calendar.
