HALLOWEEN / EID AL-AHDA

Halloween (a shortening of All Hallows’ Evening), also known as Hallowe'en or All Hallows' Eve,^, is a yearly holıday observed around the world on October 31, the night before All Saınts’ Day Much like Day of the Dead celebrations, the Chrstıan feast of All Hallows' Eve, according to some scholars, incorporates traditions from pagan harvest festivals and, festivals honourıng the dead particularly the Celtic Samhain , other scholars maintain that the feast originated entirely independently of Samhain, Typical festive Halloween activities include trick-or-treating ,attending costume partıes, carving jack-o’-lanterns, lighting bonfires, apple bobbıng, visiting haunted attractions, playing pranks, telling scary stories, watching horror fılms, as well as the  religious observances of praying, fasting and attending vigils or church services.
According to some scholars, the observance of Halloween combines pre-Christian and Christian traditions;^, other scholars maintain "that Hallowe'en, as the eve of All Saints' Day, originated entirely independently of Samhain and some question the existence of a specific pan-Celtic religious festival which took place on 31st October/1st November."^,Historian Nicholas Rogers, exploring the origins of Halloween, notes that while "some folklorists have detected its origins in the Roman feast of  Pomona, the goddess of fruits and seeds, or in the festıval of the dead called Parentalıa, it is more typically linked to the Celtic festival of Samhaın,derived from the Old Irish Samuin meaning "summer's end, Samhain was the first and by far the most important of the four quarter days in the medieval Irish and Scottish^, calendar^, and, falling on the last day of autumn, it was a time for stock-taking and preparation for the cold winter months ahead.^, There was also a sense that this was the time of year when the physical and supernatural worlds were closest and magical things could happen.^,To ward off these spirits, the Gaels built huge, symbolically regenerative bonfıres and invoked the help of the gods through animal and perhaps even human sacrifice.^,]
It is important mainly from a traditional aspect and fun aspect for those in North America. Modern celebrations do not have a very religious overtone; it is a time for being a little bit silly
            EID AL-ADHA

Eid al-Adha,  commemorates the prophet Abraham’s willingness to obey Allah by sacrificing his son Ishmael. According to the Qu’ran just before Abraham sacrificed his son, Allah replaced Ishmael with a ram, thus sparing his life.

One of the two most important Islamic festivals, Eid al-Adha begins on the 10 day of Dhu'l-Hijja, the last month of the Islamıc calendar. Lasting for three days, it occurs at the conclusion of the annual Hajj, or pilgrimage to Mecca. Muslims all over the world celebrate, not simply those undertaking the hajj, which for most Muslims is a once-a-lifetime occurrence.

The festival is celebrated by sacrificing a lamb or other animal and distributing the meat to relatives, friends, and the poor. The sacrifice symbolizes obedience to Allah and its distribution to others is an expression of generosity, one of the  fıve pıllars of Islam
