Dasting thing I just found.
Jan 6, July 13, September 15
I searched for 6/13/15 and this is the first thing that showed up
Ephesians 6:13-15
New International Version
13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15 and with your feet fitted with the readiness that comes from the gospel of peace.
