In my database, I have always had the marriage date of my maternal 3rd great grandfather, Joseph WRIGHT to his second wife, Dorothy PALMER as taking place on April 9, 1891 in Madison County, Indiana.
Secondary sources, such as Dorothy's obituary, backed up this data by stating that they were also married on April 9th.
Which is why you should always try to go back to the original sources - as in looking through my files, I found that I had the copy of the actual marriage record from the Madison County, Indiana clerk's office - and it shows that the license was issued on April 9th but the couple was united in marriage on Apirl 11th by Benjmain F. McCarty.
