Following information supplied by the AFF:

The FIE has recently changed the way that it calculates ages for the purposes of categories at the World Championships.  Basically, it now works such that if you were born any time in a particular year, that becomes your Category year (it used to be based on Sep 1).  So, if you were born in 1953, you are considered Category B (60+), regardless now of when you were born during that year.  (Thanks to Caryl Oliver, our representative on the FIE Veterans Committee for that important nugget of information).

Please also note that according to the AFF ( website Link ):

There will be no limit for athletes wishing to compete in the Commonwealth Veterans Championships in Glasgow November 16-19 2014 (similar to previous Commonwealth Veteran Competitions and Singapore 2012)
