I purchased this for my 14-year-old child, It was completed in about 2 days. It was challenging, but not too difficult. Also, it's perfectly accurate with dates.

Instructions were all pictures, so spot were a little confusing to know when to turn over. So had to undo and redo some things when we noticed. All in all my 14 year old enjoyed completing it.
