The calendar used in Rome from 45 BC through AD 1581 is the Julian Calendar, which was introduced by Julius Caesar in 46 BC.
The last BC date before AD is 1 BC. The Gregorian calendar does not have a year zero; it transitions directly from 1 BC to AD 1. Thus, 1 BC is the final year in the Before Christ (BC) designation, immediately preceding the Anno Domini (AD) era.
The Calendar designations are BC (before Christ) and AD (Anno Domini, which means 'the year of our lord'). The first use of this calendar method was 'invented', (designed), by Dionysius Exiguus approximately in 525 AD. The reason for this was to determine the correct date for Easter. He was directed to find the date by request of Pope St. John I.NOTE: in the Calendar's being used there is no year '0' there is 1 BC and then the next year is 1 AD.Recently academics (educators) have created other designations; BCE (Before Common Era) and CE (Common Era).
The year 250 AD and 250 BC refer to two different eras in the Gregorian calendar, with AD (Anno Domini) denoting years after the birth of Jesus Christ and BC (Before Christ) denoting years before that event. Specifically, 250 AD is 500 years after 250 BC. The two periods are separated by the transition from BC to AD, with no year zero in between. Thus, they represent different points in history, one in the Common Era and the other in the years preceding it.
The last date of BC was 1 BC, then the first date of AD was 1 AD, there was no zero.

BC: Before Christ AD: Anno Domini (After Christ/Latin) BC stands for "Before Christ", AD stands for "Anno Domini" which is medieval latin for "in the year of (the) Lord" - not After Death! Interestingly, there was no year zero - the calendar goes straight from 1 BC to 1 AD.

Some Muslims may use the terms BC (Before Christ) and AD (Anno Domini) in a historical context, but it's more common for Muslims to use AH (Anno Hegirae) which is based on the Islamic lunar calendar that begins with the migration of the Prophet Muhammad from Mecca to Medina in 622 CE.
In terms of the calendar: AD (Anno Domini) is in Spanish: d.C. (después de Cristo) BC (Before Christ) is in Spanish: a.C. (antés de Cristo)
No it did not. First of all, there was no year zero. Secondly, the Gregorian Calendar was not created until 1582 AD, as an update to the almost identical Julian Calendar. It existed since what would now be regarded as 46 BC, though obviously the term BC was not used then. It used a system counting from the foundation of Rome, labelled AUC and the year we call 46 BC was 708 AUC. Neither Julian nor Gregorian Calendars have a year zero in their calculations. 1 AD immediately follows 1 BC.
The Julian Calendar was created by Julius Caesar. It was introduced in 46 BC. The calendar began to be used on January 1, 45 BC, and was used until replaced with the Gregorian Calendar in 1582.
Although the Julian calendar, which is extremely similar to the Gregorian calendar, the most popular calendar now, had been in use since it was introduced by Julius Caesar in 46 BC, the system that we use now for numbering the years of the Julian and Gregorian calendars was not introduced until AD 525, and it did not become widely popular until the 9th century.
Asked on 4 Jan 2013 AD, so 31688 years ago it would have been:2013 AD - 31688 = -29675 ADNegative AD dates are BC, but when Dionysius Exiguus devised the AD/BC calendar (in the year 247 Anno Diocletiani, which he called 531 AD) zero (0) had not been invented, so 1 AD was preceeded by 1 BC, so -29675 AD becomes 29,676 BC.
