Have you heard about Arbor Day and would like to find out what exactly this day is all about and how you can celebrate it?

Then you’ve come to the right place: we’ve summarized everything you need to know in our ultimate guide to Arbor Day.

Let’s dive straight into the day of the trees.

What is the day of the tree?

Before we look at how tree love can be celebrated, let’s first tell you what Arbor Day actually is.

In the simplest sense, Arbor Day is a day when we celebrate trees.

We don’t want to bore you with a long philosophical monologue about the importance of trees (although our founder Chris would really love that!).

Thank you for the picture, Maja!

So let’s just say: Arbor Day is the perfect opportunity to let out the tree hugger in you.

So, now you know what the day of the tree is. But do you know when it is?

When is the day of the tree?

In Germany, Arbor Day is celebrated every year on April 25.

Did you know that this decade is very important for the environment? Some of the world’s brightest scientists are warning that now is our last chance to save our planet.

In this article about the “Twentrees” (the decade that will save our planet), you can find out more about why it is still worth remaining optimistic and what role trees play in climate change.

Tree love around the world – When is Arbor Day in other countries?

The date of Arbor Day varies in different countries. Some countries even celebrate trees for whole weeks!

Here is a rough overview of the dates on which Arbor Day is celebrated in other countries.


In Australia, Arbor Day is celebrated on June 20.

And because Australians really understand the importance of trees (have you ever been to the outback?!), they also celebrate a National Tree Day (on the last Sunday in July) and a National Schools Tree Day (on the last Friday in July), in addition to Arbor Day.

And hey, if that’s not enough, the Australian state of Victoria is celebrating a whole week of trees.


Let’s plant a tree, shall we?

Canadians celebrate their National Forest Week during the last full week in September.

The actual day of the tree is on the last Wednesday in September (also known as Maple Leaf Day in Canada).

And then there are a few states that love trees so much that they simply need a few extra days.

Ontario celebrates Tree Week from the last Friday in April to the last Sunday in May.

Prince Edward Island marks its Arbor Day on the third Friday in May, during Arbor Week.

And Calgary celebrates trees on the first Thursday in May.


In the USA, National Arbor Day is always celebrated on the last Friday in April.

The very first Arbor Day was celebrated in the USA on April 10.

The current date for Arbor Day was not decided until 1970. At the 100. To mark the 50th anniversary, President Richard Nixon set the date for Arbor Day for the last Friday in April.

Great Britain

In the UK, National Tree Week is usually around the end of November.

The story of the day of the tree

In Germany, the first official Arbor Day was celebrated on April 25, 1952.

On this day, Federal President Theodor Heuss and the President of the German Forest Protection Association (SDW), Federal Minister Robert Lehr, planted a maple tree in Bonn’s Hofgarten.

Since then, Arbor Day has been celebrated on the same day every year and millions of trees have been planted by nature lovers throughout Germany over the past 70 years.

But that’s enough history now! Now it’s time for our fun facts and 12 super activities to celebrate Arbor Day!

Three fun facts about the Day of the Tree

So, now all the statistics and figures are out of the way. And because we don’t just make sustainability easy at Click A Tree, but fun too, here are three day of the tree fun facts.

1. the oldest day of the tree in the world

The oldest Arbor Day in the world is not the one in the United States, as so many people would assume. Although it was founded in 1872 and is therefore already 150 venerable years old, the oldest Day of the Tree was celebrated in Mondoñedo in Spain in 1594.

2. the oldest tree in the world

Exactly which tree is the oldest tree in the world varies from time to time. However, the spruces in the northern Swedish mountains are definitely among the oldest known trees. Twenty of them are estimated by scientists at Umeå University to be over 8,000 years old.

The North American Scots pine “Sinus aristata var.longaeva” is estimated to be only a comparatively young 4000 to 5000 years old.

3. worldwide names for the day of the tree

The theory is now complete, are you ready to celebrate?

The most common activity on Arbor Day is, of course, planting trees.
