At the recommendation of the mysterious TDH, I visited
http://www.scopesys.com/anyday/
...and found this under an amazingly long list of events which happened on my birthday:
Religious Observances
Ang : Commemoration of St Crispin (Ang) Christian : Feast of St Gaudentius, bishop of Brescia Christ : Commemoration of SS Chrysanthus & Daria, martyrs (3rd cen)
Not only do I get one of the most famous speeches from Shakespeare for my birthday, I also get to commemorate the martyrdom of Daria, she of the pierced navel which miraculously healed.
