Use tags for previous and next days

I am trying to display yesterday, today, and tomorrow short form (e.g., Sun Mon Tue). I know I could use a variety of bitmap fonts to accomplish this, but it also seems like it should be relatively easy to accomplish with tags. However, every expression I have tried (e.g., ([DAY_WEEK_S]-1)) just displays the text formula. I am knew to tag expressions, so maybe I’m doing this wrong. Is there an easy way to have text for t-1, t, and t+1? Thank you
