What was year 1?


The year of epoch for the Anno Domini calendar era is AD 1 (I), 1 AD or 1 CE. It was the first year of the Common Era (CE).

The first century was the years 1–100, the second century was 101–200, and so on up to the 20th century (1901–2000).

Secondo l’International Standard, la data dovrebbe essere scritta come anno, mese e giorno: YYYY-MM-DD. Pertanto, se gli Australiani e gli Americani usassero questo, scriveranno la data 2019-02-03.
