Why did Timothy McVeigh choose April 19th for the bombing?

Timothy McVeigh chose April 19th for the Oklahoma City bombing to coincide with the second anniversary of the federal government's siege at Waco, Texas, which resulted in the deaths of 76 members of the Branch Davidian sect. He viewed the date as symbolic, representing what he perceived as government overreach and tyranny. McVeigh sought to make a statement against the federal government, and the timing of the attack was intended to maximize its impact.
