How can one determine the correct day of the year, based on a 365 day year?
I can use ‘DAYS360’ to find the number of today’s date
=DAYS360(1/1/2006,9/20/2006,FALSE) will yield ‘259’. But the actual day
number based on a 365 day year is 263. I don't care about a 360 days year (I
don't live there!). Again, how can I calculate the actual day number based
on a 365 day year?
PS Why does this formula yield ‘38420’ instead of ‘259’?:
=DAYS360(1/1/2006,TODAY(),FALSE)

A1: 9/20/2006
A2: =A1 - DATE(YEAR(A1),1,0)

Because your start date is a very small number:

1/1/2006 = 1 divided by 2006 = 0.000498504

Your Days360 function reduces to:

=DAYS360(0,TODAY(),FALSE) which is the number of days since 12/31/1899 or
38420.

If you want the string to be interpreted as a date, inside a function, you can
use:

=DAYS360("1/1/2006",TODAY(),FALSE)
or
=DAYS360(DATE(2006,1,1),TODAY(),FALSE)

One way:

=INT(A366-DATE(YEAR(A366)-1,12,31))

1/1/2006 is the equivalent of 1 divided by 1 divided by 2006

Try it this way:

=DAYS360("1/1/2006",TODAY(),FALSE)

Based on a 365(6) day year:

=TODAY()-DATE(YEAR(TODAY()),1,1)+1

Trevor,
I do not understand the A366 portion of the equation.
Thanks,

That's just the cell with the date in it ... maybe an unfortunate choice
;-)

Could just as easily be:

=INT(A2-DATE(YEAR(A2)-1,12,31)) where A2 has the date in it

Alternatively:

=INT(A2-DATE(YEAR(A2),1,0))
day 0 of month 1 this year = day 31 of month 12 last year
