You may have noticed the different ways we speak about time:
BC, BCE, BP, AD, CE,
What do they all mean?
BC and BCE mean exactly the same, with BC meaning Before Christ and BCE standing for Before the Common Era. The only difference being that the latter (BCE) does not hold any religious significance.
BP refers to Before Present and is also commonly used. It was created in the 1950s so basically means the number of years before then.
AD means Anno Domini (it is Latin and translates into ‘in the year of the Lord’). It refers to the years after Christ was born. Again, CE refers to the years of our Common Era but like its counterpart (BCE), it does not have a religious connotation.
