All the churches seem to say that they believe in Jesus. Jesus was born and raised in the Roman Empire, but Jesus never mentioned any of the names in the Roman calendar. Jesus believed in following the Scriptures.

Suggestion: Maybe change the names to suit yourself:

Days of week – Sunnyday, Moneyday, Chewingday, Weddingday, Thirstyday, Fryingday, and Sittingday.

Months – Janet, Fabian, Marsh, Apple, Maybelline, Juno, Julia, Augment, Septic, Octagon, Novice and Decimal.
