2023 Review

Danube Day 2023 marked the 20th annual Danube Day celebration, bringing together citizens from more than a dozen countries to celebrate their shared river waters. The event’s longevity attests to the important contribution of rivers towards the economy, environment, and culture of the region.

While the 2020 and 2021 Danube Day celebrations had to accommodate COVID-19 safety restrictions by holding online events, since 2022, we have seen the return of outdoor events throughout several Danube countries! This year’s theme is “Keep the Danube Blue,” inspired by the 4th Joint Danube Survey (JDS4), one of the world’s most comprehensive surface water monitoring efforts. The findings of JDS4, first published in 2021, have been disseminated throughout the Danube River Basin to inform the public about vital data on water quality across the Danube River and its major tributaries.

The Danube Day poster design for 2023 features the motto Keep the Danube Blue”, this time against a blue background. Like every year, our signature Danube Day branded bags have been sent out to our partners throughout the Danube River Basin to distribute to the public.
