You can treat the BC years like negative numbers except that you need to compensate for the fact that there is no year 0 (the year before A.D. 1 is 1 B.C.). If you add to a B.C. year and you get a number greater than -1, add 1 more to compensate for the lack of year 0. For example, to calculate what year was five years after 2 B.C., add five to negative two:

-2 + 5 = 3

Since 3 is greater than -1, add 1 more:

3 + 1 = 4

So A.D. 4 is five years after 2 B.C.

Likewise, when you're subtracting from a positive (AD) year and you get a number less than 1, subtract 1 more for the lack of year 0. For example, to find the last leap year BC, subtract 4 years from the first leap year AD:

4 - 4 = 0

Since 0 is less than 1,

0 - 1 = -1

So the last leap year BC was 1 BC.

Do you add or subtract BC from present year?

To convert a year in BC (Before Christ) to the corresponding year in AD (Anno Domini), you add the BC year to the present year and then subtract 1. For example, if the current year is 2023 and you want to convert 500 BC, you would calculate 2023 + 500 - 1, which equals 2522. This method accounts for the lack of a year zero in the transition from BC to AD.


What is BC vs AD?

BC= stands for Befor Christ(count down) AD= stands for nAnno Domini(in the year of the lord) You know when years counted down right? Well that is BC. Then AD is when the years count up. When the abbreviations are the same then subtract(-) if they are different the add(+) 500 BC And 500 AD its 1,000 years! Now do you get it? If you still dont get it.... ASK YOUR TEACHER!


How many years separate 500 BC to AD 500?

To calculate the years between 500 BC and AD 500, you add the years in BC to the years in AD. There are 500 years from 500 BC to 1 BC and another 500 years from AD 1 to AD 500. Therefore, the total is 500 + 500 = 1000 years.


How many years between 10 BC and 10 AD?

There are 19 years between 10 BC and 10 AD. The reason for this is that there is no year 0 in the Gregorian calendar system, so the year following 1 BC is 1 AD. Therefore, you need to count from 10 BC to 1 AD (10 years) and then add the 9 years from 1 AD to 10 AD, totaling 19 years.


What year was it 100000 years ago?

2017 - 100,000 = -97,983 As there was NO year 0 (as zero hadn't been invented when Dennis the Little renumbered the years in what he/we call 531 AD) 1 BC preceded 1 AD and so subtract an extra year → 100,000 years before 2017 AD is 97,984 BC

How do you compute the difference between the year BC to AD?

Add the two year values together and subtract 1, to allow for the fact that there was no year zero. So from 1 BC to 1 AD is 1 year. 1 + 1 - 1 = 1. From 10 BC to 40 AD is 49. 10 + 40 - 1 = 49.

How many years is it from 27 BC to 476 AD?

Oh honey, that's an easy one. You just subtract 27 from 476 and voilà, you get 503 years. But remember, we're talking BC to AD here, so don't forget to add 1 year for that sneaky little zero in between. So, the grand total is 504 years. Hope that clears things up for ya!

How many years between 400BC and 1500AD?

To find the number of years between 400 BC and 1500 AD, we need to calculate the difference between the two dates. First, let's convert 400 BC to BC to AD: 400 BC is equal to 400 years before the start of the AD era. Since the AD era starts at 1 AD, we add 400 years to 1 AD to get: 400 BC + 400 years = 1 AD Now, we can calculate the difference between 1 AD and 1500 AD: 1500 AD - 1 AD = 1499 years So, there are 1499 years between 400 BC and 1500 AD.
