 :The lady with which I am most familiar Alexandra Feodorovna (Alix of Hesse) was married on 14 May OS and became empress on that date. The coronation of both her and Nicholas took place on 30 May OS. Henry VIII and Anne B. married on 25 January and she was crowned on 1 June 1533. So the quick answer is No, the coronation and the wedding do not have to take place on the same day and it is probably true too in the Hapsburg empire and the medieval Hungarian era. Regards,   "
