 Zimbabwe Africa Southern Does not observe DST


On 8 February 2018, the European Parliament voted to ask the European Commission to re-evaluate DST in Europe.[13] After a web survey giving high support of not switching clock twice annually[14] on 12 September 2018, the European Commission decided to propose to put an end to seasonal clock changes (repealing Directive 2000/84/EC)[15] In order for this to be valid, the European Union legislative procedure must be followed, mainly that the Council of the European Union and the European Parliament must both approve the proposal.
