13 Things About the Number 250 and Some Notes on the 250th

Colleen at The Thursday 13 holds a weekly blogging prompt where bloggers make a list of 13 things on Thursdays. The topic is for you to choose. 

Last week, one fellow participant borrowed the graphic I created for my posts, so I decided to use one of the ones she's used on her posts. The colors go well with my topic for today.



In honor of the US 250th birthday, I chose the number 250 as the topic for today. 

  1. The Roman numeral for 250 is CCL.
  2. The Ferrari 250 GTO is a sports racing car dating back to the 1960s.
  3. In space Bettina is asteroid number 250. It was discovered by the Vienna Observatory in 1885.
  4. The numerology energy represented by the number 250 resonates with intuition and introspection.
  5. 250 is a 5-smooth number, meaning that its divisors are all less than or equal to 5.
  6. In terms of telephone codes, in North America 250 is the area code for the Canadian Province of British Columbia, and it is the international dialing code for the African nation of Rwanda.
  7. The food additive E-250 is Sodium Nitrite, which is classified as a preservative. According to some sources, the E-250 additive is considered dangerous.
  8. Beware of the number 250 in China as it is often used as an insult to describe someone as being stupid, slow-witted or inappropriate. (See here).
  9. The British Parliament celebrated its 250th in 1957, and the Taj Mahal reached its 250th milestone in 1898.
  10. Harvard's 250 anniversary was in 1888. Yale's was in 1951, and Princeton's in 1996.
  11. In biblical contexts, the number 250 appears in several significant passages, often associated with events of rebellion, judgment, and divine authority. 
  12. Angel number 250 is a combination of the vibrations of the numbers two, five, and zero. These digits carry different energies and offer a deeper understanding of the meaning behind angel number 250.
  13. Semiquincentennial is just one word used to mean 250th anniversary. See below.

Some side notes:

Semiquincentennial is derived from the following Latin roots:
  • Semi: Half
  • Quin: Five (specifically derived from quinque)
  • Centennial: A hundred years
  • Essentially, it means half (0.5) of a quincentennial (500 years), equaling 250.

Alternate names for "250th anniversary" include "Sestecentennial." The etymology for this one is:

  • Sestertius: Meaning "two and a half" (from semis, meaning "half," and tertius, meaning "third"). The Romans used this to count units; literally "halfway to the third".
  • Centennial: Derived from centum, the Latin word for "hundred".

"Quarter-Millennial" is also used, as 250 years is one-fourth of 1,000 years (millennium).

"Bisesquicentennial" has also been used. This is derived from:

  • Bi- (two) + sesqui- (and a half) x centennial (100 years) = 250 years.
  • This term was used by Princeton University in 1996, Reading, Pennsylvania in 1998, and Washington and Lee University in 1999.

US History Quiz

Last week for my trivia class at work, I chose to use US history as a topic, with the 250th birthday of the US coming up. I watched the video below, then wrote questions based off the ones in the video. 



One guy who participated knew most of the answers. He seems to like history. I hated having to take it in school because I had to do it so many times and it was so repetitive. What was considered important to learn then now just sounds like trivia.

How many of the questions did you know?
