Spain's Nazi Time Zone Myth Debunked by Astronomer

Spain has been running an hour ahead of its natural solar time since 1940, and the story behind it is finally getting corrected.

For more than eight decades, a popular myth claimed that dictator Francisco Franco changed Spain's time zone to honor Nazi Germany. The tale seemed believable: Franco's regime made the switch in March 1940, aligning Spanish clocks with countries much farther east instead of matching neighbors Portugal and the UK on Greenwich Mean Time.

But Pere Planesas, a former astronomer at Spain's National Astronomical Observatory, spent years studying historical records and found something different. "The often-repeated interpretation that it could have been a gesture towards the Nazi government is a hoax," he told Euronews.

The real story is less dramatic but more interesting. In 1940, countries across Europe were adjusting their clocks to save energy and coordinate activities during World War II. France, Belgium, the Netherlands, Portugal, and the UK all made similar changes around the same time.

Spain's government order specifically mentioned aligning with other European countries that had already moved their clocks forward. Germany actually made its change a month later, in April, meaning Spanish time never matched German time during that period anyway.

After the war ended, some countries like the UK switched back to their original time zones. Spain and France kept Central European Time because it made practical sense for a recovering continent. Coordinating transport, communications, and trade across shared time zones helped European reconstruction efforts.

Why This Inspires

What makes this story hopeful isn't just correcting a historical myth. It shows how Spain today is having an honest conversation about what serves its people best, weighing history against health and convenience.

Health experts like Dario Acuña, a physiology professor at the University of Granada, point out that Spain's current time zone means excessive evening light in summer, which can disrupt sleep patterns and the body's natural rhythms. The biological clock responds to sunlight, and late sunsets mess with melatonin production needed for rest.

Yet Planesas notes that changing back now would create years of complications. Spain shares its time zone with most major European trading partners and more than half the continent. Custom matters too. After 85 years, Spanish society has built its rhythms around these clocks.

The debate continues between maintaining European coordination and respecting the sun's natural schedule. Either way, Spain is thinking critically about inherited systems and whether they still serve the common good.

Sometimes the most inspiring progress is simply choosing truth over comfortable myths.
