Downing Street has announced that Article 50 will be triggered on March 29 - and, if history is anything to go by, it's a good choice.
Taking a look back through history, March 29 has been a great day for Britain, with several momentous events taking place.
Could this mean that Brexit is the right decision after all? Well we certainly wouldn't go that far, but at least the date is a sound choice.
Check out some of the events that have taken place on March 29:
1461 - Edward IV beats the Lancastrians to secure English throne
Maybe not a great day to the sons and daughters of the red rose, but a momentous day in English history nonetheless. Edward IV and his band of Yorkies defeated the Lancastrians at the battle of Towdon, securing Edward's place as king. He's generally regarded by historians as having been a good and able king, who oversaw numerous advances in English society - notably the arrival of the printing press.
1903 - London-New York news service begins
Tired of all those stories about Donald Trump? Well be thankful that you're getting that kind of news at all.
At the dawn of the 20th century, news from America could take weeks to trickle across the pond to Britain, but that all changed thanks to the creation of a regular news service between London and New York, carried on the Marconi wireless.
It was a major breakthrough in the history of journalism, and paved the way for all that lovely fake news we have today.
1941 - Battle of Matapan ends in an Allied victory
The battle lasted for three days at the height of the Second World War. British warships were able to destroy five Italian vessels off the coast of Greece.
The British army only lost one torpedo bomber during the entire battle, according to the Word War Two Database, and it was Italy's worst defeat at sea.
The Duke of Edinburgh was mentioned in Despatches for operating the searchlight on the battleship to pick out enemy targets.
1945 - V1 bomb attacks end on Britain
The V1, known as the buzz bomb, was the first guided missile used in the Second World War.
The bombs were developed by the German Luftwaffe and mainly fired from the French and Dutch coasts, spreading panic among the people of Britain.
But the locations were finally overrun by Allied Forces - bringing an end to the V1 terror.
1981 - First London Marathon is completed
6,700 people turned out to complete the marathon on a drizzly London day, but applications for the race exceeded 22,000.
The youngest participant was a 15-year-old girl and it is believed 80% of those who attended completed the course, according to the BBC.
That first race was organised with a budget of just £100,000 to enable the supply of foil blankets, portable toilets, coffee and plastic cups. Today it is one of the world's most popular mass sporting events and a landmark occasion for millions of tourists.
2014 - First same sex couples get married in Britain
Gay marriage became legal at midnight, with many couples taking the opportunity to get married on the day, the BBC said.
Comedian Sandi Toksvig and her partner Debbie also renewed their vows on this day in celebration, with thousands of people, including other celebrities, gathering to watch the event.
In a tweet the Prime Minister at the time David Cameron said: "Congratulations to the gay couples who have already been married - and my best wishes to those about to be on this historic day."
