From 2000 to/until 2010

What's the difference between {i]"from 2000 to 2010", "from 2000 until 2010", and "from 2000 through 2010"?

The first two expressions: 

  • from 2000 to 2010 
  • from 2000 until 2010 

are the same. They both refer to a period of time that began at some point in the year 2000 (we don’t know exactly what point) and ended in the year 2010 (again, we don’t know at exactly what point in that year). 

These two sentences, therefore, mean the same thing:

  • We lived in Hawaii from 2000 to 2010. 
  • We lived in Hawaii from 2000 until 2010. 

Some native speakers of English report that “from 2000 to 2010” sounds slightly more natural to them than "from 2000 until 2010," so it might be a better choice if you are trying to choose between the two forms. However, both forms are correct and acceptable – there is no wrong choice. 

The third expression, “from 2000 through 2010,” is different. “Through 2010” means until the end of that year. Therefore, “from 2000 through 2010” refers to a time period that began sometime in the year 2000 and lasted until the very end of 2010. 

I hope this helps.
