1 CE was exactly 2,009 years ago. The year preceding that was the year 1 BCE.
To calculate the number of years between 1200 BCE and 60 CE, you add the years before the common era (BCE) to the years in the common era (CE). There are 1200 years from 1200 BCE to 1 BCE, and then an additional 60 years from 1 CE to 60 CE. Therefore, the total is 1200 + 60 = 1260 years.
The first century CE began at the beginning of 1 CE and ended at the end of 100 CE. The first century BCE ended at the end of 1 BCE, and the second century CE began at the beginning of 101 CE. (Note that there is no year 0, so 1 BCE immediately precedes 1 CE.)

BC (Before Christ) and CE (Common Era) are both systems used to label years in the Gregorian calendar. BC refers to the years before the estimated birth of Jesus Christ, while CE counts the years from that point onward, beginning with year 1. CE is often preferred in secular contexts to avoid religious implications, as it aligns with the same timeline as AD (Anno Domini, meaning "in the year of our Lord"). Essentially, the two systems represent the same time periods but with different cultural connotations.
There are a thousand years in one millennium. 1 millennium = 1000 years 1 century = 100 years 1 decade = 10 years
1 CE was exactly 2,009 years ago. The year preceding that was the year 1 BCE.
The 1200s were the 13th century, from 1200 to 1299.
To find out how many years ago 475 BCE was, you add 475 years to 2023, which gives you 2,498 years ago. BCE (Before Common Era) counts backward to the start of the CE (Common Era), which begins with 1 CE. Therefore, 475 BCE was approximately 2,498 years ago from the current year, 2023.

The time span from 1000 BCE to 500 CE is 1500 years. This includes 1000 years from 1000 BCE to 1 CE, plus another 500 years from 1 CE to 500 CE. Therefore, the total duration is 1500 years.
The beginning of the Common Era (CE) is 1. This is also called AD by Christians (after the Lord). 3500BCE is 3500 years before the CE began + 2013 years later (CE). That is added together to make 5513 years.
1-1.8 million years ago was approximately 0.2-0.8 million years ago.
Today is 2009 AD (CE), meaning that 2,008 years ago the year was 1 AD (CE). The year before 1 AD (CE) was 1 BC (BCE). So, BCE was 2,009 years ago. CE started from the estimated first year of Jesus Christ's birth.
To calculate the years between 400 BCE and 100 CE, you need to add the two time periods together. There are 400 years from 400 BCE to 1 BCE, and then 100 years from 1 CE to 100 CE. Therefore, the total is 400 + 100 = 500 years apart.
The difference between 250 BCE and 250 CE is 500 years. BCE (Before Common Era) counts backward from year 1, while CE (Common Era) counts forward from year 1. Therefore, you add the years from 250 BCE to 1 BCE (249 years) and then from 1 CE to 250 CE (250 years), resulting in a total of 499 years between the two points.
it was about 1 billion years ago.
1 Gyr is 1 billion years, so 2.8 Gyr is 2.8 billion years ago.
