Baha'i

Bahá'u'lláh (1817-1892) founded the Bahá'í faith on the belief of the oneness of God, religion and humanity. Adherents value universal principals such as love, equality, social justice, honesty, kindness, etc. while accepting social and scientific changes in their day-to-day lives. Followers of the faith take personal responsibility for their spiritual growth. The Bahá'í faith is governed by spiritual assemblies made up of nine or more members and does not have clergy to guide worship.

In the Bahá'í calendar, there are 19 months of 19 days each with four intercalary days (five in leap year). Each month represents an attribute of God. The first month starts with the New Year and the last ends with 19 days fast. The Bahá'í day starts at sunset.

Ridvan
The Festival of Ridvan (lasting for 12 days), termed by Bahá'u'lláh the 'Most Great Festival' and the 'King of Festivals', commemorates the twelve days that Bahá'u'lláh spent in the garden of Ridvan outside Baghdad. The festival commemorates Bahá'u'lláh’s public declaration of His mission to His family and closest followers.
