assuming this photo was taken with your phone, and it never left the phone, and it has been there on the phone since it was taken, you can see that info in a few different ways.
The first is by going to google photos app and organizing by date and looking for it. You will see when it was taken.
The second is to view the photo and then go to the options of the photo and go to info.
If that doesn't show anything, then putting the photo on your computer and then right clicking it and going to properties then to the details tab should tell you.
If you don't have access to a computer for this, then using a file browsing app on your phone such as AndroZIP will also do this.
