Letter for today: April 19, 2025, is 'S'

This CGI script is simply for helping me keep track of a pattern of study I use to read up on topics I have made lists of for myself. When possible, I focus on topics that correspond to the letter I assign for the day of the present month.

Simply explained, for the first day of the month, I assign 'A'. For the 26th, I use 'Z'. For the twelfth, I use 'L', and for the remaining days of the month I assign random letters.
