There is no year 0 in the transition from BC (Before Christ) to AD (Anno Domini). Therefore, the period between 1 BC and 1 AD is just one year.
No. There isn't any period of time between the two. No time was lost.
Somewhere around the year 105 A.C.
Around 2/3rds of modern Mexico
The year that comes before 1AD is 1BC. there's no 0 (Zero) AD.
Yes, the first year of our current systems was 1AD. There was no year zero. Zero is nothing, so it cannot have something attached to it. 1BC preceded 1AD. There was no year in between these two. It is just like there is no day between the last day of one month and the first day of the next month. Right from the 1st of January 1AD we were in the year 1AD though the year was not complete until it ended. Your starting point of zero was at the very beginning of the year. The year prior to that zero point was the year immediately before it, so there is no intervening year. We went from 1BC to 1AD, not from 1BC to year 0 to 1AD.

The 1st of January 1AD.
AD, or Anno Domini, means 'the year of our Lord' and began the year of Christ's birth.
Because there was no year '0'; If you were born in 1BC you would be turning 2015 in the year 2016. If you were born in 1AD you would be turning 2014 in the year 2016.
