Jerusalem Rosh Hashana 6a

דא"ר חנינה שמות חדשים עלו בידם מבבל
R'Hanina said: the names of the Months were brought with them from Babylon

The Gemmorah explains the process of adopting the Babylonian names instead of Biblical ones. The WIKI on Babylonian_calendar states that although every month is associated with a deity, Tammuz specifically bears the name of their god.

WIKI also says that the name of the god was widely known (and even worshipped) by the Israelites:

The cult of Ishtar and Tammuz may have been introduced to the Kingdom of Judah during the reign of King Manasseh and the Old Testament contains numerous allusions to them. Ezekiel 8:14 mentions Tammuz by name: "Then he brought me to the door of the gate of the Lord's house which was toward the north; and, behold, there sat women weeping for Tammuz. ..."

Ezekiel's testimony is the only direct mention of Tammuz in the Hebrew Bible, but the cult of Tammuz may also be alluded to in Isaiah 17:10–11:

What are the potential Halachical problems and does anyone deal with that?

    @JoshK Right, but the quality of the question would be much better. Isn't it what we al demand?

    @TurkHill We have Biblical serial numbers for weekdays and months. Nothing necessitates adopting foreign practices. But because they admit that they did, I suppose, they adopted the whole of the Babylonian calendar including the calculations, thus suggesting that there was no established Biblical calendar prior to the Exile.

    @RabbiKaii No, because the tradition to use the names of deities for months was well established in many civilizations, like ours (Greeko-Roman), for example, August, July, and more. When the names were adopted, Tammuz was already a deity.

    @AlBerko what I mean is, for example, Tammuz is the name of an angel, and then later it was worshipped as a diety and later we made a calendar and Tammuz was the relevant angel of the month etc. Therefore who cares if it was at some point a diety. The moon was worshipped but we still include it in a lot of our holy service

Be on guard concerning all that I have told you. Make no mention of the names of other gods; they shall not be heard on your lips.

  • @KapinKrunch Well, the simple meaning of the pasuk is that you shouldn't even mention a name of an idol. Aug 22, 2019 at 13:15
