"The history of the names of the months is an intriguing topic. Most of Europe adopted the Roman names and some of them are trivial: September (seventh), October (eighth), November (ninth), and December (tenth). (Though one would wish the numerals to have reached twelve.) But there is nothing trivial in the division of the year into twelve segments and the world shows great ingenuity assigning names to them." - Maitani from Bookmarklet

"The Romans dedicated most of their months to the gods and one doesn’t need a dictionary to guess who was honored in January or March. (We still have janitors and plenty of martial arts.) February and May are less transparent to modern speakers, but the principle behind naming them was the same. Before the Anglo-Saxons adopted the names still in use, they had their own system. King Alfred’s calendar looked so:" - Maitani

The link finally opened for me and I got to read it. Now, of course, I'm going to be really worried about April. OTOH, I'm pleased that the 2 guesses I had about how it was named were not far off the guesswork of scholars. I should've known something tricky was up when I noticed that April is rarely introduced as a month named after a god or number like the other ones. - Anika

The Anglo-Saxons sure were fond of their eths. I guess they used them all up back then :) - Eivind
