I answered a similar question a couple of days ago, People were excited about 2/22/2022, but did anyone care when the date was 11/11/1111? Did that type of format even exist, and if not when did it happen?

Basically no, since they hadn't invented that date format yet. Depending on where in the medieval world you were, the year might not have been 1111, November might not have been the 11th month, and November 11 might not have been the 11th day of the month. And on top of all that they hadn't even borrowed Arabic numerals yet!
