International Open Data Day – March 5, 2025

If you believe all kinds of data should be accessible to everyone, then International Open Data Day, which takes place on a date set yearly by the Open Data Organization, is just for you! This year, it takes place on March 5. Open data is a concept that is grounded in data being free and accessible to everyone at any given time. This day was created over a decade ago with the aim of celebrating the use of open data all over the world.

History of International Open Data Day

Before we talk about the day itself, we have to give you a quick, deeper understanding of the concept of open data. With technology transcending as the days go by, our lives are becoming more on display, and the important data we need seems to be more hidden. The open data concept seeks to eradicate that entirely.

Open data is the ideology that some data should be free and easily accessible, as well as being available for use and republishing by anyone without copyright or patent restrictions. Simply put, the open data concept allows the free access and use of data.

The type of data being considered can range from maps or scientific formulae, to very important data like medical data and open government data (O.G.D.). This automatically means that this concept can be used for just as much harm as it can for good. However, advocates of open data encourage free access and re-use of this data with no restrictions, but control of the type of re-use, thereby eradicating the possibility of important data being used for wrong reasons.

It first appeared in 1995 but had been a topic of conversation in the research world long before that. Researchers, scientists, analysts, and developers believe that open access to data will create an increase in productivity in the fields of science and technology. This is because people from all over the world will be freely able to see and re-use data to expand research in these fields.

International Open Data Day was proposed and founded in 2010, and since then, it has gone a long way to encourage the use of open data in communities. The date is chosen annually by governing group members and the outputs are open for use and re-use by anyone.

  2. Organize an event

    If you’re a teacher or a member of any company that relies on the knowledge and use of data, you can organize your very own open data event. The Open Data Organization has ways you can go about making your event stand out. Visit their website for more information.

  3. Learn more about open data

    We have only given you the tip of the massive open data iceberg. Take some time today to do some digging yourself. There are tons of information and resources online to educate you about the entire concept and how it applies to you.

5 Facts About Data That Will Shock You

  1. It’s quite recent

    Over 90% of the data we currently used was created in the past two years.

  2. Google answers a lot

    On average, Google processes over 40 thousand search queries per second.

  3. It can reach the Moon

    If the data created each day was burned onto D.V.D.s, they would be able to be stacked up to reach the Moon twice.

  4. Facebook users create a lot of it

    An estimated 30 billion pieces of content are shared between Facebook users daily.

  5. It’s larger than you think

    We create just as much data that’s been there from the beginning of time until 2003, every two days.

Why We Love International Open Data Day

  1. The open data concept is important

    Open data as a general concept is, in itself, important to all of us. It allows us to have free, easy access to data to use and reuse as we see fit. This day encourages the use of open data as an essential tool for the growth of communities.

  2. It’s important to research

    One of the ultimate benefits of open data is that it gives room for the expansion of research. The accessibility of data results allows scientists, researchers, analysts, and so on, to see and build on this existing data which increases overall research.

  3. It promotes transparency

    We are living in an age where we don’t really know the kind of data collected about us or what it’s even used for. This day promotes transparency of our data, and more so for open government data.
