We have a hash indexed by name and an array indexed by the day of year. Both contain the same information represented in two different ways.

If you want I can write a separate script that will preprocess the data files and make two files: one for the hash and one for the array.

How to slurp to a hash?

A possible idea about the design is to print a calendar, however it would take too much space for some common names. As you found, Maria has name days spread over a year.

Another idea is to keep the existing output format, but highlight the country names with bold or italic typeface. What is your opinion about it?
