Tawfiq Canaan (1882–1964) described the use of such a calendar among Palestinians in southern Palestine, as did his contemporary Gustaf Dalman, who wrote of the practices of Muslim agriculturalists who used Christian designations for the fiftieth day, "which in turn overlaid far more ancient agricultural practices: grape-watching, grape-pressing, sowing, etc."
Tawfiq Canaan (1882.-1964.) je opisao uporabu takvog kalendara među Palestincima u južnoj Palestini, a također i njegov suvremenik Gustaf Dalman koji je pisao o običajima islamskih poljoprivrednika koji su rabili kršćanske oznake za pedeseti dan, "što je, opet, odražavalo daleko starije poljoprivredne prakse: čuvanje grožđa, muljanje grožđa, sjetvu, itd.".
