I have seen all the suggestions for extracting the day of the week from a long date in a SP workflow. I would love to be able to set my date/time variable to a long date but the system will not let me. What is the problem?
Like Amal said you can just change how it appears in your form. I would suggest making custom forms to do this. You can find date formats here: Custom date formats. Unless I am misunderstanding what you are trying to do.
make that workflow variable as string data type. You can able to access those dropdown values
