class="hidden"><dl><dt><p>How often does a leap year occur?</p></dt><dd>Leap years occur every four years to help synchronize the calendar year with the solar year.</dd></dl><dl><dt><p>What is the main reason we have leap years?</p></dt><dd>To account for the Earth's rotation around the Sun. It takes Earth approximately 365.25 days to orbit the Sun once. Leap Years account for this extra quarter day.</dd></dl><dl><dt><p>Which of these years was NOT a leap year?</p></dt><dd>While most years divisible by four are leap years, centuries are not unless they are divisible by 400. Therefore, 1900 was not a leap year, but 2000 and 1600 were.</dd></dl><dl><dt><p>If a year is divisible by four, it is a leap year. What is the exception to this rule?</p></dt><dd>If the year is divisible by 100, but not by 400. This rule keeps our calendar aligned over very long periods of time.</dd></dl><dl><dt><p>In what month does the leap day occur?</p></dt><dd>Leap Day is added to the end of February, making it February 29.</dd></dl><dl><dt><p>Who introduced the leap year?</p></dt><dd>The Romans. Julius Caesar introduced leap years in the Roman Empire over 2,000 years ago.</dd></dl><dl><dt><p>What is a person called who is born on February 29?</p></dt><dd>All three terms are commonly used for people born on February 29.</dd></dl><dl><dt><p>When do people born on Leap Day typically celebrate their birthdays in non-leap years?</p></dt><dd>Either February 28 or March 1. The choice depends on personal preference or legal considerations.</dd></dl><dl><dt><p>Which famous composer, born on a leap day, composed the opera "The Pirates of Penzance"?</p></dt><dd>Gioachino Rossini. He was born on February 29, 1792.</dd></dl><dl><dt><p>In Irish tradition, what happens if a man refuses a woman's leap day proposal?</p></dt><dd>He must give her 12 pairs of gloves. This tradition was supposedly intended to hide the woman's embarrassment of not having an engagement ring.</dd></dl></div> </div> <section class = "main-section col-sm-12" id="mainaside"> <div data-drupal-messages-fallback class="hidden"></div> <div class="h5p-iframe-wrapper"><iframe id="h5p-iframe-4531" class="h5p-iframe" data-content-id="4531" frameborder="0" scrolling="no" lang="en" title="What Do You Know About Leap Years?"></iframe></div> <div class="views-element-container block" id="block-views-block-related-quizzes-block-1"> <h2>Ready to take your next Quiz?</h2> <div class="quizzes-top-blocks js-view-dom-id-f970afb5a8b888c83fde1146927ea90cd311c4c5c63bcac6baac59511f898f6d"> <div class="featured-quizzes"> <ul> <li class="featured-item"><div class="views-field views-field-nothing"><span class="field-content"><div class="item-wrapper"> <a href="https://www.infoplease.com/quizzes/arts-and-culture/easter-quiz"> <picture><source srcset="/sites/infoplease.com/files/styles/large/public/2022-02/quiz-time.jpg.webp 1x" media="all and (min-width: 0em)" type="image/webp"><img src="/sites/infoplease.com/files/styles/large/public/2022-02/quiz-time.jpg?itok=Z5We7mZi" width="480" height="480" alt="Easter Quiz" /></picture> <div class="content-wrapper"> <div class="content-category">Arts and Culture</div> <div class="content-title">Easter Quiz</div> </div> </a> </div></span></div></li> <li class="featured-item"><div class="views-field views-field-nothing"><span class="field-content"><div class="item-wrapper"> <a href="https://www.infoplease.com/quizzes/arts-and-culture/how-well-do-you-know-us-radio-stations-part-i"> <picture><source srcset="/sites/infoplease.com/files/styles/large/public/2023-08/iStock-1354169883-min.jpg.webp 1x" media="all and (min-width: 0em)" type="image/webp"><img src="/sites/infoplease.com/files/styles/large/public/2023-08/iStock-1354169883-min.jpg?itok=PdUgDZUo" width="480" height="320" alt="U.S. radio" /></picture> <div class="content-wrapper"> <div class="content-category">Arts and Culture</div> <div class="content-title">How Well Do You Know U.S. Radio Stations?
