Hi Arun,

Welcome to Gramps

I believe you are looking for the wikipage on Date Handler's ( Different cultures and regions tend to have specific and different conventions for parsing and displaying dates. )
http://gramps-project.org/wiki/index.php?title=Date_Handler

Also look at the following page about providing translations for GRAMPS:
http://gramps-project.org/wiki/index.php?title=Portal:Translators

As well as:
http://gramps-project.org/wiki/index.php?title=Relationship_Calculator

http://gramps-project.org/wiki/index.php?title=Calendar_tools_holidays

Regards
Dale Athanasias
