THE world is marking the 75th anniversary of D-Day which signalled "the beginning of the end of World War II".
But do you know what the 'D' stands for?
According to the National British World War II Museum, D stands for "day".
The D designation was traditionally used for the day of any important military operation or invasion is to be initiated.
The day before June 6, 1944, was known as D-1 and the days after were D+1, D+2, D+ and so on.
UTracks has a new walking trip in northern France which traces the historic sites of World War II's Battle of Normandy and is ideal for travellers who want to explore the area on foot, away from the history tour buses.
It starts in Arromanches, where the Allied forces established the artificial Mulberry harbour, and finishes in Bayeux, close to the Commonwealth Memorial and Bayeux War Cemetery.
Whilst the focus of the five-day self-guided itinerary is firmly on sights of historic importance, Normandy is also known for its beautiful landscapes and rich culinary traditions.
The last stage of the trip takes walkers through the centre of Bayeux with its striking cathedral and historic houses, as well as the world-famous, 70-metre long tapestry, which depicts the Battle of Hastings and dates back to the 11th century.
The walk costs from $940 per person on a twin share, B&B basis.
