Extensions start the day the original subscription ends or the day the extension is purchased, whichever comes last. For example, if your course expires on August 1, but you purchase an extension on July 1, before the course expires, the extension will start August 1. If you course expires on August 1 and you buy an extension on September 1, the extension starts September 1.
