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.
- 1Normalize the day
Gregorian and Julian labels are mapped to the same continuous day number.
- 2Apply the observance rule
For example: first Wednesday of Eastern April, or first Friday of Eastern December.
- 3Return 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.
