National For Twelves Day – April 12, 2025

The uniqueness of the number 12 shines bright on National For Twelves Day, which is held, on April 12 each year. Since we’re measuring time in two 12-hour sets, buying eggs by the dozen, and counting down the 12 months of the year, it is pretty safe to assume that this number has very special significance in many different ways. This particular day, however, is in honor of all the “12s” on a football team, also known as the fans! According to the founders of this day, the fans’ loyalty and constant support have inspired the foundation of this fun day.

History of National For Twelves Day

Before we had numbers, the world used lines to write. Places like Egypt and Greece used |, ||, |||, and Asia wrote with ―, =, ≡. Since counting these lines and slashes would have taken forever, symbols eventually became the new numbers. Over time, as remembering each symbol also got confusing, multiple civilizations independently came up with a system to count objects, but these symbols would only represent the major numbers. And then, in around the 7th century, Indian mathematicians created a system of counting called the ‘decimal system,’ that could represent any number using only ten unique symbols — the numbers zero to nine.

As life got more complex, there was a necessity to count more too, usually to numbers higher than ten. The number 10 — which was an important number in the decimal system — was then used to derive names for many higher numbers in the English language. That’s where the name ‘twelve’ comes from — it is a derivative of the Old English ‘twelf’ and ‘tuelf,’ which meant “two is left after counting to 10.”

The passage of time granted the number 12 immense significance in various areas, including math, astronomy, religion, and even mythology. The Western and Chinese zodiacs have 12 signs, there are 12 stations of the Moon and the Sun, and Jupiter takes 12 years to orbit the Sun. On the mythical side, Hercules had to perform 12 heroic labors to make amends for another Greek God’s actions, there were 12 Titans, and before them, 12 Olympians. Religion also prominently features this number in Christianity (Jesus Christ’s 12 Apostles), Hindusim (Sun God Surya has 12 names), and Islam (Prophet Muhammad had 12 legitimate successors), among others.

Twelve is also a significant number in sports, particularly in soccer and American football. The fans are the 12th player of the 11-member teams in these sports — this is so ingrained in the sport that Bayern Munich, Hammarby, Feyenoord, Atlético Mineiro, Flamengo, Seattle Seahawks, Portsmouth, and Cork City will not even allow their field players to wear number 12 jerseys because they are reserved for the fans. With so much affection for this number, is it any surprise that the inventors of this day are also athletes? The Honolulu Sea Hawkers established National For Twelves Day in 2019 to recognize all the number 12s on every football club — the fans!
