How can I drop the year from mm/dd/yyyy data?

[tobesus]

I have a large data set consisting of values from multiple years that I would
like to analyze by time of year. ie: I want to look at the month/day for each
value while ignoring the year.

Specifically I want to end up with a graph showing time of year (in months)
across the x-axis and showing all my data points as if they were from this
one hypothetical year.

Seems like it should be simple but I can't seem to crack it. Any help is
greatly appreciated.

Hi,
Try Format > Cells > Custom:
dd/mm

Hi
use
=YEAR(A1)
in a helper column

Thanks! This gets me closer but what I actually want to keep is the month
and day.

So is there some way to do a formula like: =MONTH/DAY(A1) ??? -obviously
that formula doesn't work, but you get the idea.

I'm starting out with 1/18/98, 5/4/96, 8/23/99....

And would like to end up with 1/18, 5/4, 8/23....

Just changing the cell format to mm/dd doesn't work because excel still
incorporates the year when you try to make a graph based on those values.

Help? Thanks!

=month(a1)

will give you the month for any given date (ie not year specific)

if you want day and month then try using

=text(a1,"mmdd")

this would turn 23rd September any year into 092

Hi
try
=TEXT(A1,"MM/DD")

Try this
=CONCATENATE(DAY(A1),"/",MONTH(A1))

Thanks! This CONCATENATE method and the =TEXT(A1, "MM/DD") both work. So
3/15/04, 5/21/99.... now read 3/15, 5/21.... just like I wanted.

Now my problem is that I need excel to recognize these new values as dates
again so I can graph them as month/day. I've tried re-formatting the cells to
the appropriate date format, but it won't graph them properly.

Any ideas on how to complete this second step? Thanks again.

Hi
this is not possible
Either you have date values formated according to your specification or
you have a text value.

You may try using the date values and format them within the chart

With your first date in cell A2, enter the following formula in cell B2:

=DATE(2004,MONTH(A2),DAY(A2))

Copy down to the last row of data

Create the chart using the dates in column B, and format the dates to
show only the month and day.

That's great! THANK YOU ALL!
