Calendar Puzzle "Rotterdam"

This is the last puzzle I designed.

The inspiration comes from Rotterdam: its buildings and its mentality of "niet lullen maar poetsen" (actions speak louder than words).

Twelve puzzle pieces with iconic Rotterdam buildings leave three squares open that together form a date.

On Monday January 1, the solution below would be good, because only the squares and and are open.

This calendar puzzle comes in a cardboard gift box with a large window.

The Calendar Puzzle

Which iconic Rotterdam buildings are on the puzzle pieces?: See these cards for a memory game
Can I flip a puzzle piece?: The challenge can be solved without flipping a puzzle piece, meaning you can see all the buildings. If you want to make it easier, you can flip the puzzle pieces, so on some puzzle pieces you don't see the buildings.
Is there a solution for every challenge?: Yes, every challenge has a solution.
Is every challenge equally difficult?: No, some challenges are more difficult and others are easier.
How many different challenges are there?: A year has a maximum of 366 days and each date can be on 7 different days of the week. So the number of different challenges is 7 × 366 = 2562.
What can I do if my question is not listed here?: Use the Contact Form to ask your question.
