Important days have been celebrated by crowds in a number of countries, and all these activities have pros for these areas. In my perspective, all those days have financial benefits for these countries.
People around the world have prepared parties for specific days throughout the year. First, these days have positive aspects for society. People have the opportunity to sell some souvenirs to tourists, like bracelets, which are famous in that country. In addition, people have the opportunity to share their feelings and foods throughout the celebration. They can even find their sweethearts. Some business people can sell their products, like meat and jewelry. The majority of people prefer to eat food like vegetables which include vitamins or want to buy a glamorous thing like a bracelet for their family.
In my own opinion, people can motivate their emotions at these times. Even single people have a chance to know more people and, if they want, they can share their feelings. Moreover, many countries can become famous around the world by showing their special days, like fire nights, on TV, and these might be effective because they have a chance to attract tourists around the world. Also, if they bring a party, some charities can earn money by organizing a competition, like a sprint, on these days to help reveal the environment. For example, they can buy trees for planting in the habitats, and all these could be jungles in the future.
All in all, all these days have positive aspects for society. Many people have a chance to have a fun time, but people also have a chance to sell their souvenirs to tourists, and they can earn money. Also, countries like France could become famous around the world by inviting reporters from foreign countries to report on these festivals, and they have a chance to attract many tourists in the future.
