I know this might be embarrassing but.

<p>I forgot how A.D and B.C.E and B.C works.
how do they work again?????</p>

<p>Like which A.D. or B.C.E. and B.C are we on?</p>

<p>We're AD.</p>

<p>AD stands for the Latin Anno Domini meaning in the year of our Lord (referring to Christianity).</p>

<p>Likewise, BC stands for Before Christ.</p>

<p>BCE I believe is Before the Common Era, and is used in conjunction with CE (Common Era) in place of AD.</p>

<p>so b.c.e and b.c have different meaning but same thing right??</p>

<p>Like 100b.c.e or 100 b.c. would be 1st century</p>

<p>Yes, 100 BC and 100 BCE refer to the same year.
Same for AD/CE.</p>

<p>100 BCE does mean the same thing as 100 BC, and both are in the 1st century. </p>

<p>In any case, BC and AD carries a religious context as explained by amoreni. </p>

<p>Many textbooks now have switched to BC and CE (Common Era). </p>

<p>


</p>

<p>wait then why is some timelines like</p>

<p>220 b.c.e - 306 b.c.e??</p>

<p>b.c.e. And c.e are just secular verions of BC and AD. And I've never seen a timeline like that because that would be going backwards? Odd.</p>
