I was wondering what the original names of the months in Latin? The earliest one that I can find is from TimeAndDate:Roman Calendar:
Months in the Republican Calendar
Month Names Number of Days
Ianuarius 29
Februarius 28
Martius 31
Aprilis 29
Maius 31
Iunius 29
Quintilis 31
Sextilis 29
September 29
October 31
November 29
December 29
The link doesn't provide the names in the ancient Roman calendar, which had only 10 months.
There are inconsistencies in the names of months.
The names for July and August were named after ordinal number + -ilis suffix,
The name for April was named after something not exactly an ordinal number + -ilis.
The names for September, October, November and December were named exactly the same as they were in Modern English. Their etymology also show that their roots were cardinal numbers not ordinal numbers, besides that they have suffixes different from -ilis.
The names for March, May and June were named after the names of gods and goddesses.
In the ancient Roman Calendar, were the names of the 10 months named all after ordinal numbers, similarly to the names for July and August, with a suffix -ilis? What were their names then?
How were the names of the months changed afterwards?
Note: Due to censorship, I cannot access much of the internet or Wikipedia.
