Using Norton's trial software, days counted

Hi all!

 

Norton's trial software could be used for 30 days. How is the days counted? If the software is installed, let’s say, October the 1st, and uninstalled a few days later. Then the software is installed again a few weeks later. Will the trial expire around November the 1st or it is counting the days actually installed?   I receive this question today, and couldn't answer...

 

Thanks and regards,
