hello  
for some reason, the Date.strptime is mixing up my date. pl see here.  
the date changs from “6/13/2008” to “2020-06-13”

irb(main):001:0\> require ‘date’  
=\> true  
irb(main):006:0\> entry=“6/13/2008”  
=\> “6/13/2008”  
irb(main):007:0\> Date.strptime(entry,’%m/%d/%y’)  
=\> #\<Date: 4918027/2,0,2299161\>  
irb(main):008:0\> nowdate=Date.strptime(entry,’%m/%d/%y’)  
=\> #\<Date: 4918027/2,0,2299161\>  
irb(main):009:0\> nowdate.to\_s  
=\> “2020-06-13”

you ned %Y, not %y (note the capitalization). im guessing that since  
%y means yy, its only taking the first 2 digits of your year (20) and  
using that as the year.
