When did the Battle of the Bulge end?

The story behind the answer

It concluded on January 25, 1945, when Allied forces had pushed the Germans back to their original lines in the Ardennes, erasing the “bulge” created by the surprise offensive that began on December 16, 1944.

This was Nazi Germany’s last major offensive on the Western Front, aiming to split Allied armies and seize Antwerp. Fierce fighting at Bastogne, the 101st Airborne’s stand, and relief by Patton’s Third Army—along with clearing weather that restored Allied air power—turned the tide. Remember it as a six-week winter battle that ran from before Christmas to late January: Dec 16 to Jan 25. The other dates mark different WWII milestones—Pearl Harbor (Dec 7, 1941) and Hiroshima (Aug 6, 1945)—not the Ardennes campaign’s end.
