CVs tend to be somewhat more formal, so I would use the extra ink and spell it out.

Even in contexts where abbreviations are appropriate, English doesn't use a leading zero before the digit representing the month. So in a compressed format like a table or an outline, or in a casual piece of writing like an e-mail, you would write

8/93 - 6/94


In a résumé or business letter, though, I agree that you should probably be more formal, which means writing out the month (without a comma):

August 1993 - June 1994


If absolutely necessary, you could abbreviate as follows:

Aug. '93 - June '94

However, that doesn't really save you much space anyway.

If it's a standard period such as a school year, it may not even be necessary to mention the months specifically, since presumably it's self-evident that you had a summer vacation:

1989-93 . . . B.A. in English, X College
1993-94 . . . M.A. in English, Y University

(sorry I can't do tabs here)

... to abbreviate the way hm-us just did:
Aug '93 to June '98

It's better to stick with the three letter abbreviation:
Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec

hm-us is right on the rest of the stuff, tho.

Sorry, that's not quite correct. The three-letter computer abbreviations are suitable for compressed formats such as spreadsheets where the number of characters must be limited. However, in standard text (in AE), May, June and July are not abbreviated because they are already so short, and the abbreviations for the other months are written with periods.

See the Chicago Manual of Style, 15th ed., section 15.42 (p. 570) for a complete list of abbreviations of months and when to use them.

What can I say hm-us ... you seem to be always right!!! Man lernt nie aus ... I guess maybe I should start reading such books like the "aforementioned" Chicago manual of style, instead of going by common usage ... Too bad my favorite reading is actually TV-Guide ...

I am still agood fisherman ...
