Global movement to end violence against women

VDAY

This annual campaign founded by Eve Ensler uses a single letter and a holiday for its name.

This clue refers to V-Day, a worldwide campaign founded in 1998 to raise awareness and stop violence against women and girls. The answer "VDAY" is short for both "Victory Day" (symbolizing triumph over violence) and "Vagina Day" (tying to the movement’s roots in The Vagina Monologues). It’s often written with a "V" hand symbol, making the abbreviation a concise fit for crosswords.
