The five holy evenings on the Muslim calendar are called Kandil (Candle). Regaip Kandili - The beginning of the pregnancy of Prophet Mohammad’s mother is on Thursday, July 3.

Kandil

It is necessary to add that Turks have a personal way of following Islam. A great number of Muslim Turks will enjoy a nice alcoholic beverage, smoke cigarettes and make the most of the "good things in life", though taking care not to do these during religious occasions such as Ramazan (Ramadan) or the Kandil. This is, of course, an unofficial declaration on your researchers part. Ramazan is the holy month when for thirty days a good Muslim lets nothing pass his/her lips during daylight hours; no eating, drinking, smoking or even licking a postage stamp. Some restaurants and nightclubs are closed during the month of Ramazan.
Mosque festivals are called Kandil, which means Candle. It is so called because all the mosques are illuminated and those are the nights on which Muslims pray for forgiveness and wish to see the right way of things to be done according to their religion.

The story of Kandil

The five holy evenings on the Muslim calendar are called Kandil. During the Ottoman Empire Sultan Selim II of 16th century lit candles on the minarets of the mosques in order to announce these holy nights to the public. Since this calendar is calculated with the revolution of the moon around the earth the dates of the Kandils differ every year.
Mevlid Kandili - The birth of Prophet Mohammad (March 19, 2008)
Regaip Kandili – The beginning of the pregnancy of Prophet Mohammad’s mother (July 3, 2008)
Miraç Kandili – Prophet Mohammad’s rising to sky (July 29, 2008)
Berat Kandili – The forgiveness of the sins (August 16, 2008)
Kadir Gecesi – The Koran’s first appearance to Prophet Mohammad (September 26, 2008)

These nights Muslims usually worship and sing Mevlit, a poem written for the birth of Prophet Mohammad. Kandils were holy days when young members visited the older members of the family, however today the Kandil greetings are made with phone calls. Some restaurants serving alcoholic beverages may be closed at Kandils. Most of the pastry shops and bakery sell Kandil Simidi (special small crispy bread ring strewn with or without sesame seeds). In some apartments the neighbors hand out helva (a special Turkish dessert made of semolina or flour) or lokma tatlısı (again a special Turkish dessert made of fried dough with syrup).

Actually, this post reminded me another forum web site I used to go.
Just before last kandil, somebody posted this 'kandil celebration' in a religious way with lots of prays in Arabic.

The topic, later on turned into a discussion 'if drinking alcohol during kandil is worse than normal times'

Do you think it is worse? I mean you commit more 'sin' if you drink during religious days (ie kandil, or ramadan) ?

a blatant copy of Christianity?

I think quite some Muslim scholars would call this kind of feasts 'bidah', an innovation of Islam that is not tolerated. Because a Muslim is not supposed to worship any other than Allah, and celebrating the pregnancy or the birth of Muhammad sort of sounds like venerating that too.

Hey people, he is just the messenger, not the message

well, it is somewhat funny, considering how much they hate each other.

Actually they dont have to hate eachother
I m muslim and do not hate jewish or christians

I was told that "Ben sizin için dua ederim" I was also told 100 prayers would be said for himself also. Why 100 prayers?
