month name to number

[dadelta50]

I have a file with 2 columns - Month, Year.  The month column is the text name for the month.  I would like to create a custom column that will create a date using the month & year columns and the day will be the last day of the month.

EXAMPLE of current file:

MONTH   YEAR

October   2010

I would like this to read 10/31/2010 in the new column.

Any help is greatly appreciated.

If you want to try DAX, you can create two columns to get the values

Date_Start = DATEVALUE('Tran'[Year]&"/"&'Tran'[Month]&"/"&"1")

Date_End = EOMONTH('Tran'[Date_Start],0)

Remember to change the data type to Date

Hi @dadelta50,

By my tests, the M query of ImkeF should solve your problem.

Create a new column that returns a text string with a full date expression with this formula:

"1."&[Month] &"."&Text.From([Year])

Then just convert this column to date.

If you want to retrieve the last date within the month, you can instead use this formula:

Date.EndOfMonth( Date.From( "1." & [Month] & "." & Text.From([Year]))))
