What does "2007 - date" mean?

There is an expression in English, to date, which means until now or up to the present time.

This person has written that expression, in a sense, because the dash represents the word "to". Verbally therefore, the line would read "2007 to date".

Likewise, '2007 - 2008' would be spoken as "2007 to 2008", etc.

In Britain, it's not uncommon to see this written on résumés (or CVs, as we call them).

EDIT: Although, more often than not, it will be written "2007 - Present." This was pointed out to me in the comments.

I've never encountered that particular usage before - it looks a bit strange, but there's certainly a degree of "logic" to it.

Suppose you've listing past employment on a CV, for example. When reading such "columnar table" contents out loud, you'd say...

Programmer, 1990 to 2000
Team Leader, 2000 to 2010
Chief Executive, 2010 to date

...where the written format might look something like this...

Programmer, 1990 - 2000
Team Leader, 2000 - 2010
Chief Executive, 2010 - date

It's possible you might even be filling in boxes on a form where the dashes were already pre-printed. Since the first two dashes would definitely be read out as to, it's not completely ridiculous to imply that the third one could be treated the same way, so given to date is a standard idiomatic usage meaning up to the present time, you could save yourself writing those extra two letters by letting the dash "stand for" the missing word.

I'm thus tempted to see it as a creative, but non-standard "double-duty" usage. (Akin to my habit of using a closing bracket as part of a smiley on ELU! :)
