Looking for a pre-Roman Cathaginian calendar (Coptic ? Egyptian?) and early Roman calendar correspndence

I hope someone can help me find a month to month correspondence between months as the Cartheginians would have known them prior to their defeat by the Romans and their Roman equivalents. Did the Romans use the Egyptian calendar or a Phoenician lunar calendar?

I think this is probably as close as you are going to get. With some obvious caveats, e.g. these are mappings to modern Gregorian calendar months, it may actually be Hebrew not phonetician (but there seems to be agreement that the two calendar systems were similar and likely derived from one or the other), we don’t know if the Carthaginians used the same system just because they were phonetician, etc. etc.

Two months gathering (October, November — in the Hebrew calendar Tishrei, Cheshvan)
Two months planting (December, January — Kislev, Tevet)
Two months late sowing (February, March — Shvat, Adar)
One month cutting flax (April — Nisan)
One month reaping barley (May — Iyar)
One month reaping and measuring grain (June — Sivan)
Two months pruning (July, August — Tammuz, Av)
One month summer fruit (September — Elul)

Thanks griffin 1977. I see a lot of references to Carthaginian use of the African or Coptic calendar. Was that after their defeat by Rome? Which calendar are you referencing?

I see it’s the Babylonian calendar.

Would it be correct then to say that Hannibal Barca used the Babylonian calendar in his time?

Nitpick: It’s Phoenician. A phonetician is a specialist in phonetics.

Well, the Phoenicians did invent one of the earliest alphabets.
