Although over years could be argued, I would say 1945 as it had one of the largest global and lasting impacts and events. 1942 was the turrning point of WW2 which finally ends at the end of the year (death toll of which is millions), Allied discovery of the Holocaust death camps, dropping of nuclear bombs in Nagasaki and Hiroshima (which also led to the start of the cold war between America and Russia) and the United Nations is formed.
There is no real answer to that. Every month has very historical events and history is something that is worldwide. Something of historicial significance in one country, may not be of any importance of all in another country. The most historical events in your country may be in a particular month, but in another country, its most historical events are in another month. So taking that worldwide, there are major historical events in every month of the year, so you cannot say any one month is most important. Even within a single country, there can be disagreements on the importance of some historical events. Some are more important to some people than to other people.
