Hellouin- modern holiday tradition dating back to the ancient Celts of Ireland and Scotland, whose history began in what is now Great Britain and Northern Ireland. Celebrated on October 31, the eve of All Saints' Day. Halloween is traditionally celebrated in English speaking countries, though the official day off is not. Since the end of the XX century, during the process of globalization, the fashion for Halloween paraphernalia appeared in most non-English speaking countries of Europe and in the CIS. Halloween is celebrated informally in some other countries with close cultural ties with the US or the UK, for example, in Japan, South Korea, Singapore, Australia and New Zealand, a number of island countries in Oceania, more recently - in Russia and other countries of SGBV.
