Hi Cassius:
I am a new member of Epicurean friends. I am also a member of Epicurus Philosophy List. Vince Cook, the moderator of EPL has stated the following:
‘Epicurus's birthday, the traditional date on the ancient Attic calendar, the tenth of Gamelion, begins at sunset on January 26th this year.’Your calendar marks Epicurus’s Birthday Jan 23rd.I will appreciate your comments.Thanks
