The Yezidi Religious Textual Tradition: From Oral to Written
Harrassowitz, 2017. The calendar synopsis identifies the first Wednesday of Eastern April, the first Friday of Eastern December, and the Eastern dates of the Assembly.
Winter · regional Çêlka traditions
Batizmî is not a single universal Yazidi date. It is especially associated with Çêlka communities from the Mardin and Tur Abdin region and is observed at different times by Torî and Çolî groups.
What the calculator does
For the reference index, the Torî cycle runs from the Sunday before the first Sunday on or after 1 January through that Sunday. The Çolî cycle is shown two weeks later, following published German Yazidi community calendars. These are reference windows, not a claim that every family uses the same dates.
Regional. Always check the calendar of the relevant family, community, or religious association.
Annual index
Each year links to a permanent, server-rendered calendar page.

Calculation method
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.
Gregorian and Julian labels are mapped to the same continuous day number.
For example: first Wednesday of Eastern April, or first Friday of Eastern December.
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.
Sources & authority
Academic sources define the rules; an official regional calendar cross-checks contemporary civil dates; a community calendar supplies the labelled Batizmî windows.
