Odd??? Weird??? 2002 $5.00 Bills

I just noticed the other day that some of the 2002 $5.00 bills were printed in 2001 and some were printed in 2003. Were there any printed in 2002? And why were they printed in these years.?

None have been found that are printed in 2002.

They printed the fives a year before the release. Probably printed enough for 2002, Than needed more again to be printed in 2003.

All of the 5's I currently have in my possession show issue of 2002, but are printed in 2001 or 2003 as well
