Backup Exec 2012 Question

Hello all,

     I'm currently busing Backup Exec 2012 on Server 2008 R2 and i have a few backup tapes that were not labeled with dates on them and were left from the last employee that was in my position.  My question is, is there anyway i can find out the dates the last backup occurred so i can label them and store them correctly without catalog/restore? Or if i have to catalog and restore what steps do i have to take in order to find out the correct date the last backup happened on a particular tape? 

Thank you so much in advance
