Formerly: “Association against double summer time (DST) and for reducing the advances of legal time”
Public information website heure-ete.net, updated since 2004.
In 2026, ACHED renews its call to end “double summer time” by returning to a more natural time zone alignment: Back to the Time Zone (UTC+1 or UTC+0). Infographics, figures (billions of euros, millions of tonnes of CO₂), analyses, letters and petitions support this call. Thank you for reading, understanding, and joining urgently.
