1. In 1940, New York State made February 29 a legal day for women to propose to men. This law was largely overlooked by society, but it was a lighthearted acknowledgment of the Leap Year tradition where women were allowed to propose to men.

2. In 1952, a group of women in New York City formed the "Leap Year Club." The club celebrated every four years on Leap Day and the women were allowed to propose to their male companions. The club eventually disbanded, but in 2020, a group of women revived the organization to celebrate Leap Day once again.

3. On February 29, 2008, the New York Philharmonic performed a special Leap Day concert at Carnegie Hall. The program included works with leap-related themes, such as Schubert's "Der Erlkonig" and Stravinsky's "The Rite of Spring," which contains a section called "Leap of the Sacrificial Dance."

4. In 1692, Leap Day was dedicated to New York City's first mayor, Cornelius Van Steenwyk. The residents of the city honored him with a parade and other festivities.

5. In 1988, Governor Mario Cuomo proclaimed February 29 "Leap Year Day" in the state of New York. The proclamation recognized the uniqueness of the day and encouraged New Yorkers to celebrate and make the most of the extra time.
