This is not true. Radiocarbon dating works on anything that exchanges carbon with the atmosphere, which includes air bubbles trapped in ice cores. You can approximate the year when the exchange stopped.

Other kinds of radioactive dating work on different materials, often rock.

Augustus wasn't called Augustus until after Julius Caesar was dead.

The Roman calendar had twelve months for the entire Republican period. According to legend, Romulus invented a 10-month one that was used for a bit, but he may have never existed in the first place. It was probably an early Roman King who replaced it.

It wasn’t a fixed period. Saturnalia was the inter-calendar period, and the priests were supposed to measure the solstice and work out when to start the next year so the farming seasons lined up properly.

Because of a general failure to do this properly, for a number of reasons, Julius Caesar reformed it with a 365-day year and leap year every four.
