Could you help me, please?
1) A post on Facebook: "Trailer fresh from the oven. Thanks to who helped make it possible. Be there AT/ON the showcase day Thursday 6th to check it out"
Should I say "At the showcase day Thursday 6th" or "On the showcase day Thursday 6th""?
2) Do you use "Cold War" or "Cold War's" in this sentence: "This month's agreement has seemingly reduced the risks of a nuclear conflict on the same scale as that of the Cold War/Cold War's."
