What the calculator does

How the Cejna Cemayê date is calculated

The index uses the contemporary official seven-day listing, equivalent in 1900–2099 to 23–29 September in the Eastern calendar. The wider 23 September–1 October ritual span reported by scholars is shown as a note, not silently collapsed into one date.

Rule used 23–29 Eastern September (main seven-day index)

Whose practice does this represent?

Centred on Lalish. Attendance and the performance of particular rites depend on place, office, and circumstance.

Why some sources show a longer span: Omarkhali and Encyclopaedia Iranica describe rites from 23 September through 1 October in the Eastern calendar. The seven-day headline dates here follow the contemporary KRG civic listing; the broader ritual span for 2026 reaches 14 October 2026.

Calculation method

Transparent reckoning, not a black box

The tool treats “Eastern calendar” as the Julian civil calendar named in the cited scholarly descriptions. It converts both systems through a Julian Day Number—a continuous day count—then applies the stated weekday or date rule.

  1. 1
    Normalize the day

    Gregorian and Julian labels are mapped to the same continuous day number.

  2. 2
    Apply the observance rule

    For example: first Wednesday of Eastern April, or first Friday of Eastern December.

  3. 3
    Return the civil date

    The result is converted back to Gregorian for the annual index and displayed with its source rule.

Not a universal religious ruling. Yazidi observance is living and regionally varied. Community and religious authorities remain the authority for actual practice.

The gap is not always thirteen days. It is 13 days for 1900–2099, but changes across centuries because Gregorian and Julian leap-year rules differ. The converter calculates it rather than hard-coding 13.

No invented era year. Claims for a single ancient Yazidi year count are not consistently established in the specialist sources used here, so the tool labels Julian dates plainly.
