I doubt that anyone has been bothered by this coincidence because it's not terribly unlikely.
If there are 12 months in the year and if wars last a random amount of time, one war in twelve will end in the same month it started, and one in four will end in the same or an adjacent month. So unless the opposing sides actively collude to avoid it, a war ending in about the same month (though a different year) than it started is not especially unlikely.
