Arunima has rightly pointed out that there are many religions and festivals in India. But I would like to remind that all these festivals are celebrated in different manner and only few of them are capable of causing inconveniences to others if celebrated in an undisciplined manner. For instance, I don't think celebration of festivals like Bhai dhooj, Raksha Bandhan, palm sunday, ash Wednesday, cheiraoba or Ugaddi etc would cause inconvenience to others. Likewise, if I am not mistaken, even Id is mostly about offering feast. So its unlikely to cause inconvenience.

But I also endorse the view that certain regulations should be followed so that the celebration of other festivals do not cause inconvenience to others or harm the environment. So use of loud speakers, bursting of crackers during diwali or taking out processions during various festivals should be regulated

@suni most of the European countries follow Christianity. Don't they celebrate Christmas in the same way as we celebrate diwali or any other festival or don't they celebrate new year eve.

The difference is they have lesser festivals than ours. I am against the fire work and loudspeakers but what can be done as we raise our voice for the same then our voice will be suppressed and we will be seen as anti religious person thats the main reason I don't oppose them and let them do what they do. 

If we look at the history of the festival that why they came into existence, it was clearly to help humans specialise with each other. Restriction of a festival to one's own home or a particular place will definitely put a bar on the socialising nature of human beings. Not just India , the human race all over the world have evolved same features. Even in European countries there are several festivals where possession are carried out but there are no major problems in those countries because people there are disciplined much more than in India. Only if the people in India start acting more responsibly and show some discipline ,more than half of problems of India will get solved. So rather than putting a bar or restriction, discipline is the key.

@Sanjeev Gupta- Maybe that's true for many countries but countries like Britain, America, Australia, France, Germany, Canada etc where mixed cultures and castes live and celebrate their functions within their homes or specified areas and that too in perfect harmony. As I have mentioned in my previous post that I have yet to watch a single religious function in public in Sydney where people from all parts of the world live with various traditions and way of celebrations. I don't recall anything similar or any function in public wherever I went in other countries too except a few carnivals (on fixed rout and time).

PS- No, they don't celebrate Christmas, Easter or other festivals like we celebrate Holi, Diwali, Dashera, Muharram, Ganesh Chaturthi, Muhharam or Eid like we do. By the way all these festivals are celebrated here but no one sees them in public or streets.

Religious celebrations have lost their significance and soul nowadays , it is all hype,show and noise. Earlier families got together to celebrate festivals and it was a joyous occasion that brought people together and strengthened bonds. Now we have taken it to the streets . Large scale celebrations held by different groups , competing with each other to show theirs is the best has become a way of celebrati festivals. Religion and religious sentiments are personal and meant to be enjoyed by families . If one wants to celebrate it on a large scale , steps should be taken to make sure that it does not inconvenience others .

It is meaning less to compare India with other small countries. India is big country and its population crosses 125 crores. So here it is not possible to celebrate some religious function indoor like other country which are followers of Christianity. Here in India some festivals are celebrated on public place, like Dushara, Deepawali, morum, Gurupard. I know only about North India. Peoples are became aware for spending money enviornment. 

@Anil- Okay I will not compare India with small countries like America, Russia, Canada etc but let me share my experience of China which is bigger than India and has a rich tradition of festivals. By the way, I have never seen a public gathering for any religious purpose during my multiple visits to China.Here is a list of Chinese festivals-

Although I have never stepped out of India, there are several European countries where local festivals are celebrated. In these celebrations parades are carried out in groups, you can easily find references to these festivals on web. I agree that those celebrations might be done in a disciplined manner so that citizens don't face any problems in commute. The origin of the festival celebrations in group was done so that people get a feeling of belonging to the society. These festivals , parades or possessions act as a source of entertainment for all the people living in society who are burdened by boredom of their life.

Festivals and religious ceremonies are celebrated across all cultures across the Globe. There are Grand celebrations all over the world at some or the other occasions. But we do not hear stories of inconvenience. They are well planned out and celebrated keeping their civic sense intact. We do not have stories of someone loosing their life as they could not reach hospital in time due to some religious procession. They are assigned a place to celebrate and they have rules to follow. Rules have to be followed anywhere is any celebration of a civilized society. 

I totally agree with Usha that celebrations have lost their real soul and has become more of show off.

Today is Ganesha festival and we as an apartment have opted for a nose free celebration. There was no loudspeakers and songs to be played. The pooja was offered with vedic chanting and it went peaceful. We have gone for a small idol of Natural clay to be environment friendly. My neighbor did not check her mail and notice board. She did not realize that the celebration was going on. She was not happy with small natural idol and the silent celebration. She kept comparing it to last year and was criticizing the organizers for the low profile pooja. Throughout the vedic chanting she kept complaining about it. So where is the soul in the celebration. They want grand celebrations.

I just Google out the the top most festivals celebrated all over the world and found that celebration is grand and just like us they also come across the street and celebrate. Its not that we Indians only do that, whole world celebrate their festivals like this. But thats not good. 

Today Ganesh chaturthi is being celebrated all over India and people are thinking that they are pleasing God by singing bhajans on loudspeakers but they are wrong they are unnecessarily annoying people by their act. 

I am really surprise in this age also we are fools. As we feel good by bursting crackers and polluting environment and get happy without thing that we are making it polluted and difficult our coming generation to live in such polluted earth. How fool we are? I laugh at people and myself too.
