The Project Gutenberg eBook of Dimasalang Kalendariong Tagalog (1920), by Honorio López.
This is the book where your parent's name came from! Macario, Atanacio, Efren, Mamerto, Crecenciana and Eufrosina got their names here.
I have encountered some people who are still using this here in Cavite. When planting crops, loading chicks or pigs, they would look for the best day as written by Honorio Lopez.
