Thanks again for your help.
I installed this component in Portuguese translated much of the component. But there are missing lines to bring as is the case with this information from Author, Category, Rate us, Created date that you would like it to translate.
Would you like to know how to translate in Portuguese?

First find the string you are looking for.
Use notepad++ to search thru files and folders in the components\com_k2, or modules...., or plugins... and search for "created"
You should find the languange constant string
Next search in the language package you are using to find the constant string
If you find it create a language override and edit it
If you cont find it create a language override and add it

You can find it from the command line ie: grep -rw "searchterm" , issuing the command from where you want to start looking from
