why did the terrorist choose the date 9/11

The specific date of September 11 for the terrorist attacks was likely chosen for practical operational reasons rather than symbolic ones. The lead hijacker, Mohammed Atta, selected the date relatively late in planning, and there is no clear evidence he chose it for symbolic significance. One factor influencing the timing was that Congress was in recess during August, so the attackers wanted to ensure political targets like the Capitol would be occupied, which meant early September was ideal. Additionally, they wanted to strike quickly to avoid detection once ready. The choice of a weekday also ensured maximum casualties in the Twin Towers due to the working crowd. Overall, the exact reason why September 11 was chosen remains unknown and may have involved practical considerations like ticket availability or other operational factors rather than deliberate symbolic intent.
