Patton’s Third Army got to France about 29 days after D-Day , when his headquarters landed on July 5, 1944. That’s roughly 4 weeks after June 6, 1944.

Quick context

Patton himself was already in the European theater before D-Day, but the key “got to Europe/France” moment people usually mean is when his Third Army headquarters arrived on French soil.

Timeline

  • D-Day: June 6, 1944.
  • Third Army Headquarters lands in France: July 5, 1944.
  • Time gap: 29 days, or just under 1 month.

Why this wording matters

If you mean Patton as a person, he had been serving in the Mediterranean before this. If you mean his famous combat role in the Normandy campaign, the July 5 arrival is the relevant date.
