How can I convert a week number to an actual date?

Rich Domo Employee

This is more of a solution to a question I had.


To start, I'll tell you what I'm working with. I have a string which is my week number named `Week` and it looks like this:


  • Week 1
  • Week 2
  • Week 3

I also have an integer of the four digit year (e.g. 2016) named `Year`.


From these I wanted to create a date recognized within Domo as a date. I built this within a Beastmode, but the code applies to SQL very closely:




  WHEN `Year` = 2016

          THEN STR_TO_DATE(CONCAT('2016,',TRIM(RIGHT(`Week`,2)),',Sunday'),'%Y,%U,%W')




The String to Date function does the converstion of a string with a known or specified format into a date. The Concat puts the string elements together. Trim removes the white space and Right takes the specified rightmost characters.  The Sunday in the code specifies that for my circumstance I want the date that begins with Sunday.


If your year was a string instead of an integer like mine the above code could be further simplified. 


I hope this helps you out!
