Is "till" inclusive or exclusive? [duplicate]

Solution 1:

It's ambiguous.

Some may read it as including April 2013, others may not. I'd probably read it as inclusive.

American English uses the inclusive word through:

  • I worked at company X from April 2012 through April 2013.

For unambiguous British English, add extra wording:

  • I worked at company X from April 2012 to April 2013, inclusive.

  • I worked at company X from April 2012 through to April 2013.

  • I worked at company X from April 2012 up to and including April 2013.
