The aforementioned statement ("con el objetivo de clarificar cualquier duda relacionada a los días 25 y 27 de julio de 2018, es preciso señalar que estos días son días laborales, cónsono con el estado de derecho vigente") is in line with the announced (2017-03-24) and later amended (2017-04-28) list of official non-working 2018 public holidays in Puerto Rico, and previous reduction of the number of annual non-working public sector holidays in Puerto Rico, by lumping 4 of the annual non-working public sector holidays of Puerto Rico into one, the "Día de los Próceres Puertorriqueños" (2015-10-21, 2014-07-29, 2014-07-23, 2014-07-19, 2014-07-01, 2014-05-22, 2014-05-12 and 2014-03-19).
Although the cancellation of the annual July 25 public holiday of Puerto Rico was overturned in the Senate of Puerto Rico, last spring (2018-04-02), this reversal never passed Puerto Rico's the House of Representatives and therefore is ineffective.
Note that the cancellation of the July 25 and 27 former public holidays of Puerto Rico is also contained in the recently-released list of the 2019 public holidays in Puerto Rico (2018-07-19).
