Did christian institutions ever attempt to rename the days of the week to less pagan names?

by Andrelse

The days of the week are in english (and other languages, like german) a very old reminder of the pagan roots of these cultures. Has anyone ever tried to "modernize" the terms?

I kind of answered this in this topic, although the phrasing of the question was different. Apart from this example, I don't know of any other case, so the answer to your closed question is Yes, at least in one case.

In the 6th century, an archbishop in northwestern Iberia, under Suebi rule at the time, was sufficiently influential to change the local language from using the pagan/roman names of the days into using the ecclesiatical/also-in-latin names (feria secunda, feria tertia... - roughly translated to second day, third day and so on). The local language eventually became portuguese and due to the age of discoveries, colonialism and plain population growth, these names for the days of the week are now used by roughly 250 million of native speakers.

This was a common practice among the Religious Society of Friends (known as Quakers) starting from their formation in mid-seventeenth century England. Instead of using what they saw as pagan names for the days of the week they referred to them by numbers. So Sunday was “first day,” Monday was “second day,” and so on. Months were also changed in this manner, so instead of December you had “twelfth month.” This caused some confusion during the calendar reforms of 1752, when March switched from being “first month” to “third month.” Some contemporary Quakers keep to this practice but it has become less common.
