The oldest (though not dateable) testimony for the existence of the day dedications comes from Yasna 16, a section of the Yasnaliturgy that is – for the most part – a veneration to the 30 divinities with day-name dedications. The Siroza – a two-part Avesta text with individual dedications to the 30 calendar divinities – has the same sequence.
