Show Month from Week #


I'm creating a helper column that needs to show what month a week number was from.

For Example, I have a sheet with a [Date] column and [Week #] column.

I have second sheet that has a Week # and is pulling data from my first sheet based on a calculation using Week #.

In the second sheet, I'd like to create a helper column that displays the Month that the Week # is from, I.E. - Week 1 = January, Week 6 = Feb, etc...

Can this be done with a formula?

    The easiest way to do this is in stages on a reference sheet.

    Step 1:

    Create a date type column and enter ever date from Jan 1 to Dec 31.

    Step 2:

    Create a text/number column called "Weeknumber" and use this formula:

    =WEEKNUMBER([Date Column]@row)

    Step 3:

    Create a text/number column called "Month Number" and enter the numbers 1 - 12 in it.

    Step 4:

    Create a text/number called "Month Text" and enter the desired text for each month.

    Step 5:

    Create a text/number column to house the final desired output of the month in relation tot he week number and use this formula

    =INDEX([Month Text]:[Month Text], MATCH(MONTH([Date Column]@row), [Month Number]:[Month Number], 0))

    Now you have a table that has every date, the corresponding week number, and the appropriate month text.
