Every Day Carry is what's in your pockets when you walk out the door on your way to work or whatever.

Personal Survival Kit is a pocket sized kit that you keep on your person as opposed to in a backpack or somewhere else.

Speaking of which, I tend to think of this type of stuff in terms of equipment, tools and supplies rather than a "kit". With the exception of the firestarter, I use my EDC almost every day. When I'm camping in the woods, I need things like firestarters often, so I don't stash them away in a "kit". There is no first aid "kit" in my home - there is a cabinet with first aid "supplies". (I'm accident prone plus I have five young sons.) A "kit" is something sacred that you can't touch unless you are "surviving".
