Yes, it looks like that takes care of the error generated for a February
29th start date (and it still is significantly shorter than the formula I
posted<g); but the (probably unsolvable) problem of how to deal with
February 29th start dates when the TODAY value is before March 1st of a non
leap year remains. I guess a February 29th and March 1st leap year start
dates will always be the same number of days away from the TODAY date for
that condition. Perhaps the best way to handle this is never set a start
date of leap year... make it company policy to push a February 29th start
date to the first business day on or after March 1st.

Ok....I think I may have solved that issue:

=IF(A1,LOOKUP(365,DATE(YEAR(NOW())+{0,1},MONTH(A1) ,DAY(A1)-1)+1-TODAY()),"")

(Amusing....all this fuss to accommodate a one-day-every-four-years
occurrence.)

I
first thought... it occurs for a start date of February 29th of a leap
year
with a TODAY date between January 1st and February 28th of a non leap
year.

Hire Date: 29-FEB-2004 (or any leap year)
Today: 27-FEB-2007 (or any non leap year)
Calculated Difference = 2 days

Hire Date: 1-MAR-2004 (or any leap year)
Today: 27-FEB-2007 (or any non leap year)
Calculated Difference = 2 days

Both Hire dates produce the same difference. I mistakenly thought that
carried throughout the year, but the problem actually is how to handle
the
collapsing of the leap day into years where that date does not exist.

Perhaps I'm being dense....but....

Hire Date: 01-MAR-2000
Today : 27-FEB-2007

Per the formula: 2 days until the next anniversary date

The math:
Hire Date Anniversary: 01-MAR-2007
Less: Today's date : 27-FEB-2007
Equals : 2 days

Can you clarify what you discovered?

Startin' to look pretty good!

Upon further testing of my previous offering I find it fails if the
hire
date is a leap day so I'll put that in the round file and "stash"
this
beauty cooked up by Ron.

Nope, it is not starting to look good at all... this formula, and
Ron's
original, also get tripped up by a start date of 02/29/2000 (or any
February
29th in a proper leap year)... it happens whenever the "TODAY" date is
anywhere within the range of January 1st to February 28th.
Unfortunately,
that is the least of the problems...

As it turns out, ALL of the formulas submitted so far (including Ron's
and
its variations) will produce an incorrect calculation if the TODAY
date
is
anywhere within the range of January 1st to February 28th of a NON
leap
year
and the start date is any day on or after March 1st of a leap year...
under
those conditions, the date difference will be one day less than it is
supposed to be. To test what I am saying, try a Start Date of March 1,
2000
and a TODAY date of February 27, 2007. There should be 3 days
difference
between these days (Feb 28, Feb 29 and Mar 1), but all formulas report
2
days... and this missing day is carried forward for Start Dates up to
and
including December 31, 2007.
