Most of the aforementioned incorrect lists of 2019 public holidays in Ecuador, are based on the Decreto No.858 which, 3 years ago (2015-12-29), specified the dates of the annual non-working public holidays in Ecuador, one-off public holidays in Ecuador, and moveable public holidays in Ecuador, for the 5-year period covering the calendar years 2016-2017-2018-2019-2020.
However, since then (2016-12-13), the Suplemento Registro Oficial No.906 was approved by Ecuador's legislature (2016-12-13), at the behest of then President, Rafael Correa (2016-10-16), and signed into law by the same (2016-12-21).
The aforementioned 2016 legislation ("para que todos los años se tenga el mismo número de días de feriado y se puedan planificar las actividades") thus amended the 2003 "Ley Orgánica de Servicio Civil y Carrera Administrativa y de Unificación y Homologación de las Remuneraciones del Sector Público" (2003-12-04), by virtue of which most Ecuadorean public holidays' day off are moved to the nearest weekend, and also applies to regional public holidays in Ecuador ("Si es un feriado local, se hace lo mismo, se cambia a lunes, se hace un puente"), as well as overriding the terms of the Decreto No.858 of 2015.
