Default Convert Week number into Month

I have a worksheet with values for year and week number. I need to convert
these to the descriptive month name. Some weeks cross month ends, but this
is okay, I just need a single value for each record. It could be the month
of the first day of each week number. Using Excel 2003.

Thanks for your ideas.

Thumbs up Answer: Convert Week number into Month

Here's how you can convert the week number into month in Excel 2003:
  1. First, create a new column next to the column with the week numbers.
  2. In the first cell of the new column, enter the following formula:
    Code:
    =DATE(A2,1,1)+((B2-1)*7)
    (Assuming that the year is in column A and the week number is in column B)
  3. Press Enter to apply the formula to the cell.
  4. The cell should now display a date value. Right-click on the cell and select "Format Cells".
  5. In the "Number" tab, select "Custom" from the list on the left.
  6. In the "Type" field, enter "MMMM" (without the quotes).
  7. Click "OK" to apply the format to the cell.
  8. Copy the formula down to the rest of the cells in the column.

This should convert the week numbers into the corresponding month names. The formula works by adding the number of weeks (minus one) to January 1st of the year, which gives the date of the first day of the week. The "MMMM" format code then displays the full name of the month.

If your year is in cell A1 and you week number is in cell B2, try the
following formula:

=MONTH(DATE(A1,1,MATCH(TRUE,WEEKNUM(DATE(A1,1,ROW( A1:A366)),2)=B1,0)))

Note: This is an array formula that should be confirmed by
CTRL+SHIFT+ENTER rather than just ENTER.

Note 2: WEEKNUM does not support European standard for week number,
see
http://office.microsoft.com/en-us/ex...093371033.aspx

If you use the European standard for week numbers, you have to put
some more logic into the formula to handle the case, like this year,
where the first few days of the year is not week number 1.
In Europe January 1-3 of 2010 is week number 53.

Hope this helps / Lars-Åke

=TEXT(MONTH(DATE(A1,1,MATCH(B1,INDEX(WEEKNUM(DATE( A1,1,ROW(A1:A366)),2),),0))),"MMMM")

Which does *not* need to be array entered.

Remove the call to MONTH() and the formula will work better.
=TEXT(DATE(A1,1,MATCH(B1,INDEX(WEEKNUM(DATE(A1,1,R OW(A1:A366)),2),),0)),"MMMM")

I made a typo there. The week number is in cell B1 (not B2) of course.

This needs "ROW(A$1:A$366)" or you will get things like 6 weeks in January and the formula gets exhausted while still in November after 53 weeks.

What if your year number is in the same cell as the week number ?
