What is "gargee'an"

Qarqe'an (, sometimes spelled as Gerga'oon or Girgian) is a biannual celebration, observed primarily in Eastern Arabia ( Arab states of the Persian Gulf) and Basra in Iraq, that takes place on the 15th night of the Islamic month of Sha'ban and on the 15th night of Ramadan. Gerga'oon is marked with children dressing in traditional attire and going door-to-door to receive sweets and nuts from neighbours, whilst also singing traditional songs. The tradition has existed for hundreds of years and deeply rooted in Gulf culture.

Although the celebration of Qarqe'an shares superficial similarities with the Halloween custom of trick-or-treating, practiced in some western countries, Qarqe'an has no connection with horror and no associated origin with Halloween.
