When Harry Potter's parents died,

Harry Potter's parents died on 198 1 year1October 3 1 day.

When Voldemort arrived at their hiding place, Zhan Mu asked Lily to take Harry first, trying to fight Voldemort (sacrificing himself) and gain time for his wife and son to escape.

Although he was very talented, it happened that he didn't have a wand in his hand and was killed by Voldemort.

Later, under the protection of Lily's ancient love and life spell, Little Harry bounced Voldemort's spell back to him, making him wish he was dead.

James Potter died to protect his wife and children, which is remembered by the whole wizarding world. This day is 198 1 year, 10 month, 3 1 day.
