Matt, going back and reading your use case - I think there is a far simpler way. Look at this forum post: https://community.skuid.com/t/adjust-display-format-of-date-and-date-time-fields
Because our date picker is build on the jQueryUI date picker widget, all the possible customization to that widget are available for you. The post above shows how to limit the date shown. I think you can extend it to only show the Day. You don’t need to render it as text. You just need the date picker to limit its “read mode” display to the weekday.
