2005 Toyota Prius Battery Warranty Q? - Is time frame Calendar Date or from Date of Manufacture?

2005 Toyota Prius Battery Warranty Q? - Is time frame calculated from Year Calendar Date or from Date of Manufacture?
I am trying to find out the California 10 Year/150k time frame specifically on the Prius Battery. Can anyone tell me is the timeframe from a calendar date or the actual date of manufacture of that specific vehicle.
ie: 2005 Prius with 90k miles would be covered until January 1st 2015 or from the date of manufacture such as (Mnfg date of October 20o5) so the warranty would be good until 10/31/2015.
