World Savings Day is celebrated on October 31, 2017. The World Savings Day was established on October 31, 1924, during the 1st International Savings Bank Congress (World Society of Savings Banks) in Milano, Italy. Representatives of 29 countries wanted to bring to mind the thought of saving to the worldwide public and its relevance to the economy and the individual.
The World Savings Day is usually held on October 31 except in countries where this day is a public holiday, since the idea is for the banks to be open, so that the people are able to transfer their savings into their account. In Germany World Savings Day is held on the last business day before October 31 since this is a public holiday in some States (Reformation Day).
Nowadays the focus of the banks that organise the World Savings Day is on developing countries, where many people are unbanked. Savings banks play an important role in enhancing savings in these countries with certain campaigns and initiatives such as working with non governmental organisations in order to double the number of savings accounts held by the poor.
