Pearl Harbour - Sun, December 7 @ 00:00 (+1d, 21h, 0m)
On this day in 1941, Japan achieved complete surprise in its attack on Pearl Harbour, sinking most of the US Pacific Fleet stationed at Hawaii. Fortunately, the four American aircraft carriers were out to sea on that Sunday morning, and survived to wreak havoc on the Japanese in later battles. The United States declared war the following day, eventually winning the Pacific War in 1945.
   
Full Moon - Thu, December 4 @ 08:14 (+4d, 12h, 46m)
