Exact Answer: Three Months
The Second World War, which was fought for six long years from 1939 to 1945, was one of the deadliest wars as it saw deaths in millions. In this war, almost all the world’s major countries took part and what followed was a complete disaster; and the war ended with nuclear bomb blasts on two cities of Japan, namely Hiroshima and Nagasaki.
The war was fought between two groups. The first group was named the Allies, which consisted of countries like Poland and the United Kingdom and France and British India. Apart from this, Australia and New Zealand, along with South Africa, also supported the Allies. In contrast, the axis powers had countries like Germany and Italy which were also supported highly by Japan, Spain, and Hungary.

How Long After D’day Did The War End?
The Second World War is said to be started on the 1st of September in the year 1939. The war began with Adolf Hitler attacking Poland; as soon as Poland was attacked by the German dictator Hitler, the UK and France declared war against the German nation. Soon British India started supporting Poland as a majority of India was ruled by Britishers. In front of the Germans, Japan stood in its support along with Russia. The support of Russia in favor of Germany was surprising as Hitler always had a dispute with the Russians.
At that time, Japan was a very dominant country because of its technology. It was fighting a war against China which automatically made China an enemy of the Axis powers. In 1941, many places of Britain and the United States were attacked by the military of Japan. The United States, till that time, was not on any side. Still, as soon as Japan attacked Pearl Harbour, which was governed by the US, the American nation was forced to declare war against Japan, and therefore it subsided with the countries in the Allies.

D-day | June 1945 |
End Of WWII | September 1945 |
After the support of the US with the Allies, the Soviet Union, which is now known as Russia, came in support of Germany as it can never subside with the US. In the very beginning, the axis powers dominated the war because of the strategies put in place by Adolf Hitler. But slowly, the US, the UK, and France overpowered them.
Why Does It Take That Long After D’day For The War To End?
After the events of World War I, the European countries were divided, and the Soviet Union was founded. But soon, Poland stated that it wants to be an independent nation and doesn’t want to operate under the Soviet Union. Many other countries also started voicing their support in Poland. At this time, Adolf Hitler was killing Jews in large numbers, and his dictatorship made Germany very powerful. As a result, Germany wanted to capture Poland, but the UK knew that if Hitler succeeds then, it will soon attack all the nations.
After the attacks on America by Japan, America was looking to take revenge. But as America saw no way to defeat Japan straightforwardly, the US government decided to drop nuclear bombs on Japan. All the countries apart from Germany and Japan had already lost all their resources, and Germany was also on the verge of losing. But Hitler didn’t want to surrender and kept on fighting with the Allies.

But as soon as nuclear bombs were dropped on Hiroshima and Nagasaki, Japan surrendered and declared that the war is over. Hitler soon committed suicide and his wife because he didn’t want to get caught by his rivals. After the war was over, the United States and Russia became arch-rivals and two of the world’s biggest superpowers.
