I have seen that airlines do not follow this rule for award tickets (many give 12 months from the issue date only) but I guess this has to do with the nature such tickets.
Is it IATA resolution 735?
Page nine of
this document from Australia's consumer regulatory body says IATA resolution 735 "sets the period of validity for a normal fare interline ticket at one year from the date of commencement of the flight".
However, I found
this for Qantas, stating the ticket "expires ... 12 months from the date of issue".
