Rule 405.6e

Official source text from the 1 February 2012 Rules release

Turn-based actions don't use the stack; they happen automatically when certain steps or phases begin. They're dealt with before a player would receive priority (see rule 116.3a). Turn-based actions also happen automatically when each step and phase ends; no player receives priority afterward. See rule 703.
