"**The date, 13 November 2012, for Deepavali needs to be checked against the Indian Almanac when it is available. Should there be a change in date, the Ministry of Manpower will issue a media release to announce the change. "
I remember that year that we thought of getting married, sometime (in 1st half of the year, I think), they announced a change in the Deepavali date. We took advantage of that changed Public Holiday for our wedding. Quite fun. Everything was so easy to book for! We had everything arranged within 6mths, from buying our own place to the wedding day .
