Muslims do not usually celebrate Christmas because it is typically a Christian holiday.
The Muslims celebrate Eid al-Fitr
Eid al-Fitr marks the end of the fasting of Ramadan. This has to do with the communal aspects of the fast, which expresses many of the basic values of the Muslim community. Fasting is believed by some scholars to extol fundamental distinctions, lauding the power of the spiritual realm, while acknowledging the subordination of the physical realm.
Muslims greet each other with Happy Eid'.
The Islamic tradition also associates events with the occasion. For example, on Eid al-Fitr, the angel Gabriel descended with white clothes for each of prophet Muhammad's grandsons.
In Turkey, Ramadan celebrations are infused with more national traditions, and where country-wide celebrations, are referred to as Bayram. It is customary for people to greet one another with "Bayramınız Kutlu Olsun" or "Bayramınız Mübarek Olsun" ("May Your Bayram Be Holy"). "Mutlu Bayramlar" ("Happy Bayram") is an alternative phrase for celebrating Bayram.
Referred to as both Şeker Bayramı ("Bayram of Sweets") or Ramazan Bayramı ("Ramadan Bayram"), Eid in Turkey is a beloved public holiday, where schools and government offices are generally closed for the entire period of the celebrations.
It is a time for people to attend prayer services, put on their best clothes (referred to as "Bayramlık", often purchased just for the occasion) and to visit all their loved ones (such as friends, relatives and neighbours) and pay their respects to the deceased with organized visits to cemeteries, where large, temporary bazaars of flowers, water (for watering the plants adorning a grave), and prayer books are set up for the three-day occasion. The first day of the Bayram is generally regarded as the most important, with all members of the family waking up early, and the men going to their neighborhood mosque for the special Bayram prayer.
It is regarded as especially important to honor elderly citizens by kissing their right hand and placing it on one's forehead while wishing them Bayram greetings. It is also customary for young children to go around their neighborhood, door to door, and wish everyone a happy Bayram, for which they are awarded candy, chocolates, traditional sweets such as Baklava and Turkish Delight, or a small amount of money at every door!.
