What date is celebrated as Tesla Day in some parts of the world? The answer is July 10, Nikola Tesla’s birthday.
Tesla was born on July 10, 1856, in Smiljan, then part of the Austrian Empire and now in Croatia. The date is observed informally as Nikola Tesla Day or World Tesla Day by organizations and science communities that celebrate his contributions to electrical engineering and invention.
The observance has different official names and status depending on location. Croatia marks July 10 as Nikola Tesla Day, while Serbia observes it as the National Day of Science. In Niagara Falls, Canada, it is known as the Day of Nikola Tesla. Some celebrations extend across several days, especially in Vojvodina, Serbia.
A common mix-up comes from Tesla’s death date: he died in New York on January 7, 1943. July 10 is associated with his birth, not his death. The date also attracted global attention when Google honored Tesla with a birthday Doodle in 2009.
