I have a worksheet with one column being dates in the format of 3/2, 4/25,
12/10, etc. As I added dates I could always sort from lowest (1/1) to highest
(12/31). Now I can't seem to sort any dates that have been added in 2009. I
do not have a year attached to these dates as they are birthdays and I need
to sort by month/day regardless of year. If I highlight A2 (A1 is my column
heading) the formula box shows 1/1/2008. I have never set up the year and
there is no formula set up as I have only ever added the month/day. This is
Excel 2007. How do I fix?
 
Pete,

When you enter 3/2 or 25/4 despite not entering a year Excel recognises it
as a date and add the current year but you wont see it because of your
formatting and that's why you sort has gone pear shaped since the start of
the new year.

If you want to sort by day and month only then you need to create another
column to do this called a helper column.

Lets say your dates are in column A starting in A1. Put this in B1 and drag
down as far as there are data in columnA

=DAY(A1)&MONTH(A1)

Select both columns and sort on this newly created column and your dates
will sort as you want them.

You can then hide or delete the helper column but if you frequently add
dates then perhaps hidden is the best option.

OOPS,

That wont work, you need 2 helper columns

Column B formula

=day(a1)

Column C formula

=Month(A1)

Now drag these 2 column down and then do a sort first on column C ascending
and a secondry sort on column B ascending. Hide both the helper columns.

Mike
 
Or use a different formula in a single helper column:

=text(a1,"mmdd")
or
=(month(a1)*100)+day(a1)
 
Re the Helper Column(s). Am I just to copy everything to another column (B)
and set up a formula there? Mike, with the 2-column approach does this mean
I'll have three columns to handle my dates and I'll need to use all three to
sort (sorry, I'm confused)? In trying to let the help function of excel guide
me, and posting this same inquiry in the excel worksheet thread, the question
about "text" came up. I'm looking for the easiest (isn't everyone) way to do
this. I tried the =text(b2,"mmdd") but it didn't work.
 
Here's the formula: =TEXT(B2,"mmdd"). The b2 cell is highlighted in yellow
but no 'grab handle' to pull it down the column. Dates are changed from 1/1,
1/9 etc. to 1/0 with this formula. I'm also getting a "circular warning" at
times and when I click on circular references it shows $B$2. I'm really
stumped and never seemed to have problems in prior versions of Excel.
 
This helper column of formulas doesn't replace the original data. You can
either use an unused column or insert an empty column (usually adjacent near the
original data).

So if you put the dates in column A, then you could use column B to hold the
formula:
=text(a2,"mmdd")

If there is no autofill button/grab handle, try toggling this setting:

Tools|Options|Edit tab|Check the "Allow cell drag and drop" box.

Dave I appreciate the tips but this isn't happening. I'm using Excel 2007 and
never had issues like this in previous versions. Somehow I have managed to
changed my first date from 1/1 to1-Jan in playing with this and I can't
change it back. I have added a 'blank' helper column (C) and if enter the
formula, =text(b3,"mmdd") and pull this down it will change my dates from
xx/xx to xxxx without the "/" separating the month and day. I need the xx/xx
format.
 
This helper column is only temporary -- it's only there until you finish the
sort. You can delete it as soon as you sort all the data by this column.

If you do it lots of times, you may want to keep the column, but hide it so that
it's not confusing to the user (you???).

If you select the cell with the date and see the real date in the formula bar,
then reformat the cell to display the date in the way you like.

Thanks Dave and David. David I tried the xx/xx in the formula a half dozens
times and kept getting error message about invalid characters "/". Finally,
it does work. One last and hopefully final question though. I will keep
adding dates to this list on an ongoing basis. So you are saying I will have
to keep the Helper Column to do my sort? Wouldn't it be somehow easier to
just have the formula 'work' (by that I mean do not associate a year with the
mm/dd) every time I entered the dates?
 
If the year doesn't matter, then you could always used 2008 (so Feb 29 is
valid).

Just make sure you include the year when you type the date.
