How to Convert Ancient Era Dates Into Modern Ones

Updated on June 21, 2012


How do you convert a date in an ancient era into a BC/AD date of the Common Era which is based on the Christian Calendar?

Well folks… don’t worry! Simple arithmetic will suffice here.


A Coin From Vikrama Era
A Coin From Vikrama Era

For an Era which started in Some BC


Suppose the Era started in “A” B.C and we need to find the Christian year for the Xth year of that Era.

Let the required Christian year be B then

B = X – A

For example, the year 179 of the Vikrama Era which began in 58 BC is

179 – 58 = 121 BC

For an Era which started in some AD


Suppose the Era started in “A” A.D and we need to find the Christian year for the Xth year of that Era.

Let the required Christian year be B then

B = X + A

For example, the year 179 of the Shaka Era which started in 78 A.D is

179 + 78 = 257 AD


Variations



There may be certain variations depending on whether the months mentioned are Lunar or Solar moths.

The month is important because the traditional Indian year did not begin in the same month as th Western year which begins in January.

Another point of confusion is whether the year in the inscription is to be understood as the expired year or the current year. This is sometimes but not always indicated in the text.

For example

When we celebrate a child’s first birthday

- He completes a year according to the expired theory

- He begins the second year according to the current theory


In spite of these issues if an inscription is dated in a known Era, it is possible to pin it down within a narrow margin.

      Your wealth of knowledge is endearing and interesting.

      By the way - when ever someone turns a year older, I remind them to add a year to the number on the cake, since they burned up the first one before their first birthday! Lost a lot of friends over it! LOL

      It sound so easy, perfect explanation! But I'm sure I'll be tripping over myself when I'll try convert the date (never been good with history LOL not to mention dates... I don't even know what date is today, except that it's Friday =))
