In many articles on Back to Normandy, dates are mentioned as "D-Day + something". This table explains how those dates are calculated.
What does D-Day plus mean?
In military planning, D-Day refers to the day on which an operation is scheduled to begin. H-Hour refers to its starting time. These terms allow military planners to organize movements and activities without necessarily specifying the actual date or time.
For Operation Overlord, D-Day was 6 June 1944, the day Allied forces landed in Normandy.
Dates before the landing are written as D-Day minus a number, while dates afterwards are written as D-Day plus a number.
- D-Day -1: 5 June 1944
- D-Day: 6 June 1944
- D-Day +1: 7 June 1944
- D-Day +12: 18 June 1944
The table below continues this count through 8 May 1945 (D-Day +336), the day generally commemorated as Victory in Europe Day.
Although the Normandy campaign ended long before May 1945, the count provides a continuous chronological reference from the Normandy landings to the end of the war in Europe.
All dates are written in YYYY-MM-DD format.
