History

edit

At midday April 1, 1933, Rafael Trujillo ordered a decree that established a national time zone for the Dominican Republic, which was set to five hours behind Greenwich Mean Time (GMT). Prior to that, time in the Dominican Republic was governed by Santo Domingo Mean Time, which was 4 hours and 40 minutes behind GMT.[2]

On October 27, 1974, the Dominican Republic moved from Eastern Standard Time to Atlantic Standard Time.[3]
