A motion for relief from default and default judgment under CCP 473(b)’s mandatory attorney fault provision must be brought within six months (and a motion under the section’s discretionary provision must be brought diligently and in no case more than six months). This decision holds that “six months” means either six calendar months or 182 days, whichever is longer. Though the motion in this case was timely, it was properly denied because it was not accompanied by the proposed answer as section 473 requires.
