The International Day of Older People is observed on October 1 each year.

On December 14, 1990 the United Nations General Assembly voted to establish October 1 as the International Day of Older People as recorded in Resolution 45/106. The holiday was observed for the first time on October 1, 1991.

The holiday is celebrated by raising awareness about issues affecting the elderly, such as senescence and elder abuse. It is also a day to appreciate the contributions that older people make to society.
