To answer your question, I would need more specific information about the day you are referring to. However, I can guide you on how to find out what happened on a specific day.

1. Specify the date: Determine the exact day you are interested in. The more specific you are, the easier it will be to find details about what happened.

2. Use search engines: Enter the date along with relevant search terms (e.g., historical events, news, or famous birthdays) into a search engine like Google.

3. Explore news archives: Many news websites maintain archives that allow you to search for articles by date. You can try searching major news outlets or historical news databases.

4. Consult history books: If you're looking for historical events, check reputable history books or encyclopedias that cover the specific time period you're interested in. They often provide details about significant events.

5. Browse reliable sources: You can explore reliable websites, such as history websites, archives, or academic resources, to find information about specific events that occurred on a particular day.

Remember, the more specific you are about the date and event, the easier it will be to find accurate information.
