National Old Maid's Day celebrates the women who never get married or have children. Contrary to how it sounds, Old Maid's Day celebrates the contributions and achievements of these women in a society where women are often expected to have children and husbands to be considered "complete".

National Old Maid's Day is observed on June 4th.

Marion Richards of Jeffersonville held the first Old Maid's Day meeting in 1948. She did so to celebrate the contributions of Old Maid's to society and to their families in a time when Old Maids performed many functions in society such as teachers or nurses.
