There are a number of date systems used around the world. The most-widely used is called the Gregorian calendar, with the BC and AD date system familiar to many people. There is another calendar system used by many people around the world called the Buddhist calendar. This calendar system begins its reckoning based on the birth of Buddha. Since this religious leader was born in 543 BC (or Jesus was born 543 years after Buddha, depending on how you look at it), you can convert from one system to another simply by making the proper adjustment to the year.

In other words, the year 2002 in the Gregorian system is expressed as 2545 in the Buddhist system. Likewise, the year 2500 in the Buddhist system would be 1957 in the Gregorian system. Thus, suppose you have the Buddhist date 430611, where 43 is the year (2543), 06 is the month, and 11 is the day of the month. You can convert this to a Gregorian equivalent by simply adding 1957 to the year, in this manner, assuming the Buddhist date is in cell A8:

=DATE(MID(A8,1,2)+1957,MID(A8,3,2),MID(A8,5,2))

The formula essentially pulls the characters of the Buddhist date apart, adds 1957 to the year, and uses the DATE function to put the pieces back together into the Gregorian system.

Wouldn't the number to add be 543? 1957 was just one of the years given as an example.
