I remember my teachers in high school fighting to get the students to stop calling the years AD and instead use the religion-neutral CE. They argued that being state sponsored employees, they couldn't use anno domingo (year of our lord) as it would be a violation of the constitution's separation of church and state clause.
What about these?
Sunday: Sunne - Gemanic goddess of the sun
Monday: Mona - Gemanic moon god
Tuesday: Tiu - Norse god of war, Son of Odin
Wednesday: Wodin - Alternate spelling of Odin, Norse supreme god
Thursday: Thor - Norse god of thunder
Friday: Frigg - Norse goddess of beauty, Wife of Odin
Saturday: Saturn - Ancient Greek supreme god
January: Janus - Roman two-faced god of gateways
February: Februa - Roman day of purification
March: Mars - Roman god of war
April: Aphrodite - Greek goddess of love
May: Maia - Roman goddess of fertility
June: Juno - Ancient Roman queen of the gods
So, if we are to do away with AD as our denotation of years then I suggest we do away with all the other names with religious undertones.
Who's with me?
