Gargee'an

Gargee'an (Arabic: قرقيعان), sometimes spelled as Gerga'oon (Arabic: قرقاعون), is a semiannual celebration, observed primarily in Eastern Arabia. It takes place on the 15th night of the Islamic month of Sha'ban for Shia Muslims and on the 15th night of Ramadan for all sects. It is celebrated by children and adults alike dressing in traditional attire and going door-to-door to receive sweets and nuts from neighbours, as they sing traditional songs. It’s more of a tradition than a religious affiliation so both Sunni and Shia celebrate it. The tradition has existed for hundreds of years, and is deeply rooted in some parts of the Gulf culture, especially in Iraq, Kuwait, Bahrain and Saudi Arabia.

Although the celebration of Gargee'an shares superficial similarities with the Western Halloween custom of trick-or-treating, Gargee'an has no connection with horror and developed independently.
