The Maronite Church retains the Feast of the Epiphany as a Holy Day of Obligation but for rather unusual reasons. The See of the church is in Lebanon, which is home to Catholics, Orthodox, and Muslims, along with other religious groups. By law, the president is required to be a Maronite (catholic), the prime minister a Sunni (Muslim), and the Speaker of the Parliament a Shi'a (also Muslim). As such, "holy days of obligation" are considered legal holidays. Hence, to re-evaluate a "holy day" on the calendar and reduce its importance, would shift the balance of christian vs muslim holy days.
Our parish (here in the US) celebrated the feast yesterday. You can see from the image posted above, that in Lebanon, the feast was celebrated today.
American secular calendar publishers stopped referencing Jan 6th as Epiphany 2 years ago. I in my own way have been trying to encourage its observation since 2002. http://www.theusmat.com/natdesk.htm
