The Mandaean calendar is a 365-day solar calendar used by the Mandaean people.[1] It consists of twelve 30-day months, with five extra days at the end of Šumbulta (the 8th month). The Parwanaya (or Panja) festival takes place during those five days.[2] There is no leap year therefore every four years all Mandaean dates (like beginnings of the months or festivals) move one day back with respect to the Gregorian calendar.


Each month (iahra or yahra[3]: 220 ) is named after a constellation (manzalta[4]).[2] The Mandaic names of the 12 constellations of the Zodiac are derived from Aramaic common roots. As with the seven planets, overall the 12 constellations, frequently known as the trisar (Classical Mandaic: ࡕࡓࡉࡎࡀࡓ, "The Twelve") or trisar malwašia ("Twelve Constellations") in Mandaean scriptures,[5] are generally not viewed favorably in Mandaeism, since they constitute part of the entourage of Ruha, the Queen of the World of Darkness who is also their mother.[6]

Each month consists of exactly 30 days.[7] The Parwanaya festival comes between the 8th month (Šumbulta) and 9th month (Qaina) to make up for 5 extra days in the solar calendar.

Due to a lack of a leap year included in the Mandaean calendar, dates change by one day every four years with respect to the Gregorian calendar. Currently, for example in 2022 CE, Sarṭana, meaning Cancer, corresponds to December / January in the Gregorian calendar, instead of June / July.

Days and hours

The hours of the day are counted starting at dawn (ṣipra),[2][1]: 75  although Mandaeans formerly counted the hours of the day starting at sunset or evening (paina).[8] In Mandaic, a 24-hour day is known as a yuma, daytime as ʿumama, and nighttime as lilia.[8] An hour is called a šaia, 5 minutes is called a šuša, and a minute is called a pigia.[3]: 218–219 

Some days are considered to be auspicious, while others are ominous (mbaṭṭal).[2]

The days of the week are as follows. Habšaba (Sunday) is considered to be the first day of the week.

5 Thursday Hamša Habšaba
6 Friday Yuma d-Rahatia
7 Saturday Yuma d-Šafta (Shabta)


The four seasons are as follows, with the year starting with winter.[2] The three months of each season, given below, are also referred to in Mandaic as the beginning, middle, or end of the season.[3]: 17 


A Mandaean year is called a šidta.[3]: 219 

The Mandaean calendar is calculated from the year that Adam was born,[9] or approximately 443,370 BCE. Charles G. Häberl calculates the date 18 July 2019 CE corresponds to 1 Dowla 481,343 AA (AA = after the creation of Adam).[10] The latter half of 2023 would correspond to 481,347 AA.

All Mandaean years consist of exactly 365 days (12 regular months of 30 days each, plus the 5 intercalary days of the Parwanaya). Since Mandaean months do not have leap years accounted for every four years, seasons "slip back" and will not correspond to the same Gregorian months over time.[5]

World chronology

A chronology of the world according to Book 18 of the Right Ginza is as follows.[3]: 269–271 


According to Book 18 of the Right Ginza, there are four epochs (or eras; Classical Mandaic: dara[3]: 215 ) of the world, which is given a duration of 480,000 years.[11][12]

  1. Epoch of Adam and Hawa: 1st generation of humans (216,000 years; 30 generations according to Right Ginza Book 1)
  2. Epoch of Ram and Rud: 2nd generation of humans (156,000 years; 25 generations according to Right Ginza Book 1)
  3. Epoch of Šurbai and Šarhabʿil: 3rd generation of humans (100,000 years; 15 generations according to Right Ginza Book 1)
  4. Epoch of Noah and his wife Nuraita/Nhuraita (current and final epoch): 4th generation of humans (remaining years, which would be 8,000 years if taking the 480,000 years into account)


Mandaean festivals are:[2][13]
