April 11

All Feasts have attained their consummation in the two Most Great Festivals, and in the two other Festivals that fall on the twin days—the first of the Most Great Festivals being those days whereon the All-Merciful shed upon the whole of creation the effulgent glory of His most excellent Names and His most exalted Attributes, and the second being that day on which We raised up the One Who announced unto mankind the glad tidings of this Name, through which the dead have been resurrected and all who are in the heavens and on earth have been gathered together. Thus hath it been decreed by Him Who is the Ordainer, the Omniscient. 
(Baha’u’llah, ‘The Kitab-i-Aqdas’)
