The question assumes an initial 'big bang', which some historians, such as Christopher Browning, do not accept.
There is no exact date, as there was almost certainly no single order for the start of the 'Final Solution'. However, if you want a specific date, the obvious 'candidates' are:
Mobile killing units go into action behind German lines. The first large scale massacres take place in Kaunas, Lithuania, starting on 25 June 1941 --- or
The first mass gassings started at Chelmno (Kulmhof) in Poland on 8 December 1941.
Note that the Wannsee Conference (20 January 1942) is no longer accepted by historians, as the meeting was concerned with co-ordinating the various agencies involved. No policy decisions were taken.
The date assigned as the start of the Holocaust by the Jewish Virtual Library is 30 January 1933 when Adolf Hitler became the Chancellor of Germany. That seems like a logical starting point. They use 8 May 1945 or V-E Day as the ending point, which also seems to be a logical place to mark as closure.
There is no official start date. Obviously, Hitler didn't make a speech in public saying anything like, 'Ladies and gentlemen, I have much pleasure in annoucing that the Final Solution of the Jewish Question began this morning at 8am'. Routine gassings began at Chelmno on 8 December 1941.
Persecution had begun much earlier.
The Nazis came into power in 1933. During 1933-1941 Nazis made it practically impossible for the Jews to live a normal life. But the "Final Solution" wasn't established until 1942.
