The attack on Pearl Harbor was planned for a Sunday morning for several reasons. One reason was that Sunday was considered a day of rest for the U.S. military, and therefore, it was believed that the defenses at Pearl Harbor would be more relaxed on a Sunday morning. Additionally, Sunday was also a day when many of the ships would be in port, making them easier targets for the Japanese planes. Finally, Sunday mornings were typically quiet, which made it easier for the Japanese planes to approach the harbor undetected.
It's important to note that the decision to attack on a Sunday morning was not based solely on these factors. The Japanese military had been planning the attack for months and had conducted extensive reconnaissance on the harbor and its defenses. Ultimately, the decision to attack on a Sunday morning was based on a variety of factors, including the availability of targets and the perceived vulnerability of the U.S. forces.
