Joyful Thursday, the second Thursday after Easter, is the Ultimate of the 12 Days of Blessings, the first of the three dozenals of the Ascension Season.
The 12 Days of Blessings are a celebration of the open-minded virtue of Hope (ἐλπίς in Biblical Greek), and Joyful Thursday is a day to feast in optimistic happiness.
Hope is the virtue of open-minded thinking, the antidote of despair, and with Faith a vital half of the highest Christian virtue of Love.
