Hayek would forgive you. After all, as he'd tell you, you were radically ignorant (perhaps rationally if someone ever asked you about his birthday and you chose not to find it out) because you had lots more important information to worry about. :)
Good point. I had to tease a relative who is much happier sharing a birthday with Herr Marx than Hayek.
And, it turns out, with my dear dagny. Happy birthday again, love of my life.
I join in toasting dagny's birthday - very best regards, and here's wishing you many more joyous birthdays, each one better than the one preceding it!
At dittos to jk on the astrology thing...
dagny tells me that Wikipedia lists Hayek's birthday as May 8, not the 5th. Re-checking your original source reveals an UPDATE to that effect.
Sad to say, JK's relative (and astrology) wins again.
