Though the twelve months or rather, a year commencing from January to December is common to all, we can not ignore the years which are based on certain languages or regions.
Of course, the Jan – Dec period has established itself as an empire and the people all over the world are dependent on it for the purpose of celebrating birthdays or independence days or such important dates. Anyway, the regional years and dates are celebrated in many countries and do serve as a New year’s Day or Birthdays.

In several states, most of the people have two birthdays! Those who visit India from other Countries may get some ideas about the importance of regional dates!
