Important Dates in Recent History & Ancient History

Where events happen across a range of dates the first date is used for age calculation. If only a month is known then the first day of the month is used. If only the year is known then the first day of the year is used. The Romans used the Calendar of Numa, which included only 355 days in each year. The Gregorian calendar was introduced in October of 1582.
