Simply open your epub with Calibre Editor and update the <dc:date> entry.
For example:

Code:
<dc:date>2017-09-01</dc:date>
<dc:date>2018-09-01</dc:date>
If you have a Windows machine and don't want to install Calibre:
  1. Change the file extension from .epub to .zip.
  2. Double-click the .zip file and extract the .opf file.
  3. Update the .opf file.
  4. Overwrite the .opf file in the .zip file with the updated version.
  5. Close the .zip file.
  6. Change the file extension to .epub.
