According to author John Pearson James Bond was born on 11th of November 1920 in Wattenscheid, Germany.
Pearson wrote in “James Bond, the Authorized Biograpghy of 007“ (1973):
Bond smiled, somewhat ruefully, and paused before replying.
‘I suppose you have to know. The truth is that I’m a native of the Ruhr. I was born in a town called Wattenscheid – that’s near Essen – on Armistice Day, 11 November 1920. I have not, I hasten to add, a drop of German blood in my veins – as far as one can ever be certain of such things. As Fleming says somewhere, my father was a Highland Scot, my mother Swiss.’

Also 11th of November is the engagement day of 007 Travelers.
