"یا قلم الاعلی قل یا ملأ الانشاء... و جعلنا النیروز عیداً لکم بعدا کمالها" (اقدس/ ص 15/ بند 43)
"And we has appointed Norouz as feast for you after we completed it. ( the Aqdas, p. 15/ paragraph 43)
In Babism and Baha'ism creeds each year possesses 19 months and each month has 19 days. The total days will be 361 and because Norouz feast is Fetr feats and the first day of the Baha'i year, five extra days aren’t considered as the days of the year. Those five days are called "Ha" days. They call each Baha'i month and day with a name.
It is necessary to be noted that according to Bahaullah text the first of Farwardin and Norouz is the Baha'i Fetr feats. Consequently, when 5 extra days are added to the Baha'i 19 months, it will be 365. The last day of Al-A'la month is the fasting month coincided with the first day of the new year (Fetr feast); that is Norouz feast. Fetr feast and end of fasting month are the same.
Definitely the noble Iranians and those who have studied about Iran such as professor Gustave Le bon and professor Christen Arthur Sen know that Norouz and its related traditions and customs had been executed before the emergence of the divine religions even Islam. Also, Islam has recommended this good tradition.
So, Norouz feast as a national culture of Iranians isn’t related to the book Aqdas and the followers of the deviant cult of Baha'ism.
