Power BI is celebrating its 10th anniversary! To mark this milestone, I invite you to participate in the Power BI Christmas and holiday season Calendar. This special event features 24 unique challenges, each designed for you to solve and enjoy throughout the season.
A new challenge will be released every day, starting December 1st and continuing through December 24th. Each day presents a fresh opportunity to test your Power BI skills and creativity.
At the conclusion of the event, a winner will be selected from among the participants. Microsoft Finland has generously offered a prize, with further details to be provided soon.
Throughout December, we will maintain and announce a leaderboard, showcasing participants’ progress. Correct answers will also be shared. You will have two days to solve each puzzle; for example, the puzzle released on day one will close at the end of day two.
Day 6 – Independence day challence
This is special! Today is Finland’s Independence day. It is public holiday in Finland. President is having a reception at his castle etc. Also Finnish defence forces promote persons in reserve. Finland has one of the biggest reserve army’s in Europe. The size of the reserve is currently around 800 000 soldiers and it is about to grow to 1,2 million. Defence forces promote soldiers to new ranks if their task requires that and/or they are suitable for new task. Promotions are public information after they have been announced.
Today’s challenge is to visualize this data into map. I first thought that we would also take the PowerQuery part but that is a bit large task. It is not difficult but as a challenge just takes too much time. So I did a prebuilt dataset for you. You can download it from here: https://material.qumio.com/christmas2025/day6.zip
Your task is to visualize new promotions into map with some meaningful way and celebrate Finland’s independence day with others!
As an example I did personally this:

You can return the answer at: https://forms.office.com/e/LKyrfu3pf2 You have until end of day 7 to answer. As today is visualization task and there is no file attachment option on the return, just describe the answer.
Happy independence day.
This Holiday season / Christmas challenge is provided by Vesa Tikkanen and is not linked to Microsoft as company. I just want us to have a puzzle every day going towards the 24th of December. This is pure community effort without any business relations behind. As such I try to do this as professional as possible but please remind that this is just for us to have fun. Microsoft finland has promised some swag as a prize but they are not related to winner pickup process neither they get any details of attendance. Information regarding attendance is not being used in any other thing than picking up the winner. So no marketing, no contacting just Power BI puzzle every day.
