EU Might End DST Permanently
Next year may be the last time Europeans set their clocks forward 1 hour, as the EU considers scrapping DST permanently in 2019. The European Commission, the executive arm of the European Union (EU), has recently pushed to end the yearly clock changes in Europe.
If the initiative is successful, the last EU-wide DST period will start on Sunday, March 31, 2019. Each member state would then have the chance to decide if they stay on “summer time” (DST) year-round or change their clocks once more on Sunday, October 27, 2019 to observe permanent standard time in subsequent years. In that case, the upcoming time change would be the last joint switch from DST to standard time in Europe.
For this reason, all subsequent clock changes in European countries are now marked as preliminary on timeanddate.com.
