The twin puzzle

There were twins-Ram and Shyam with a gap of two minutes. Ram is elder by Shyam by 2 minutes; yet Shyam celebrates his birthday 2 days earlier than Ram. Why so???? Note: this has nothing to do with theory of relativity or as simple as 'uski marzi'; but a logically correct answer. Note2: The younger one celebrates his birthday BEFORE the elder one.

This has something to do with the International Date line which lies at the pacific ocean. Remember that you lose time when you move towards the west. Now as per wikipedia, the International Date Line (IDL) is an imaginary line on the surface of the Earth opposite the Prime Meridian which offsets the date as one travels east or west across it. Roughly along 180° longitude, with diversions to pass around some territories and island groups, it mostly corresponds to the time zone boundary separating +12 and −12 hours GMT (UT1). Crossing the IDL traveling east results in a day or 24 hours being subtracted, and crossing west results in a day being added.

This is more than a half answer given for the ones wondering. Now those who wish not to think and read on the interesting story, the continue reading down....

It happened that on 1st march 2008 (in australia) their mother was sitting in a ship which was crossing the pacific ocean and it was going from Canberra (australia) to Sanfrancisco (West to east). At 9:59 pm, beore crossing the international date line, Ram was born. On crossing the international date line, we have to subtract one day, thus it becomes 29th Feb 2008. Two minures later ie after crossing date line at 10:01 pm Shyam was born. Thus Shyam was actually born on 29th Feb 2008, while Ram on 1st March 2008. 2008 being a leap year, and those who are born on 29th Feb celebrate their birthday on 28th Feb, we can explain why Shyam celebrates his birthday 2 days earlier than Ram.
