The most traditional, popular celebration which the people in Nablus hold annually is that of Prophet Mohammed’s Birthday (PBUH). It is considered to be one of the most prominent and important Islamic religious celebrations in the city of Nablus. On that day, celebrants roam the streets of the old city. The Sufi banners advance in the procession of the celebrants where drums bang and copper plates tap in simple primitive tones. During the procession the owners of the shops located on both sides of the road scatter perfumes and distribute sweets and candies on the participants in the march. The decorations and colored lamp lights illuminate the streets of the old city and a number of the city's neighborhoods. Almost no place is devoid of the sound of a radio chanting the praises of Prophet Mohammed (PBUH) in addition to reciting Qur’anic verses.

Among other religious occasions, special celebrations are being held in mosques and squares in old Nablus on the eve of the Hijri New Year. The same applies to all nights of the month of Ramadan; especially, Laylat al-Qadr “Revelation Night”. This usually coincides with the twenty-seventh night of Ramadan. It is worth noting that the month of Ramadan is a special feature of the religious and cultural life of Nablus.

 New Year's Eve (Calendar) and the Easter celebrations are held in the various Christian denominations at Rafidia in particular. It is customary to organize the Christmas procession as well as lighting a Christmas tree on the night of the twenty-fourth of December (Christmas Eve) every year. This is usually performed with both officials and members of the general public. Church bells ring out across the city to celebrate this occasion. Prayers are held in all the churches of the city. The streets of Rafidia are adorned with special lighting for this occasion.

The celebrations of the Samaritans are not absent from the scene; especially at Passover. This symbolizes the release of the Israelites from the Pharaonic slavery in ancient Egypt. It takes place on the fifteenth of the first month of the Hebrew year (in the period between April 8th to May 7th of each Gregorian year). It is the herald of the end of winter and the advent of spring. The celebration is normally held on top of mount Jarzeem with the participation of the people of the city of different religions. However, due to Israeli restrictions, participation is reserved for those who hold special entry permits. Foreign visitors are nevertheless allowed without restrictions.

The residents of the city join the Samaritans in their celebrations on the Feast of Tabernacles “The Throne”. It is the anniversary of the Exodus of the children of Israelites from Egypt, where they had lived at the al-'Areesh area. It features special garnishes of the finest fruits and citruses on the interior ceiling of each Samaritan house. It must have four varieties of ripe fruits during that period; especially, pomegranate, lemon, and pepper in addition to palm leaves, bay leaves and curpery. The date of this feast is on the fifteenth of the seventh Hebrew month. It usually lasts for seven days. (September 30th - November 2nd of each Gregorian year)
