You got it. The Social War is coming. The precise date it will start is unknown. We will drift into it. Some idiot will shoot someone whose friends will shoot back.
Do you think that people who were around to experience those events knew they were living through the day a war started? Do you think folks living in Ancient Rome knew they were enduring the total collapse of an empire?
My point. The war has already started. A date will be agreed upon for when it started if the forces of evil aren't defeated, soon.
