It's a series of tasks ("puzzles") in the style of Advent of Code. Some deal with text handling, some with dates and times.
In my opinion it's a fun way to really get this stuff in your brain (by doing, not just reading about it) and especially learn about what your programming language of choice has to offer in this department.
I find the later puzzles have a bit of an artificial difficulty increase, which makes them seem a bit far fetched and unrealistic. But the first few are definitely reasonable and applicable to real-world scenarios. You also don't have to do them in order. Unlike with AoC, all the puzzles are available from the start.
