Among the Greeks and Italians he is a favorite of sailors, fishermen, ships and sailing.
As a result and over time, he has become the patron saint of several cities which maintain harbours.
In centuries of Greek folklore, Nicholas was seen as "The Lord of the Sea", often described by modern Greek scholars as a kind of Christianized version of Poseidon.
In modern Greece, he is still easily among the most recognizable saints and 6 December finds many cities celebrating their patron saint.
He is also the patron saint of all of Greece and particularly of the Hellenic Navy.

In the Eastern Orthodox Church, Saint Nicholas's memory is celebrated on almost every Thursday of the year (together with the Apostles) with special hymns to him which are found in the liturgical book known as the Octoechos.
Soon after the transfer of Saint Nicholas's relics from Myra to Bari, a Russian version of his Life and an account of the transfer of his relics were written by a contemporary to this event.
Devotional akathists and canons have been composed in his honour, and are frequently chanted by the faithful as they ask for his intercession.
He is mentioned in the Liturgy of Preparation during the Divine Liturgy (Eastern Orthodox Eucharist) and during the All-Night Vigil.
Many Orthodox churches will have his icon, even if they are not named after him.
In Oriental Orthodoxy, the Coptic Church observes the Departure of St. Nicholas on 10 Kiahk, or 10 Taḫśaś in Ethiopia, which corresponds to the Julian Calendar's 6 December and Gregorian Calendar's 19 December.

Nicholas had a reputation for secret gift-giving, such as putting coins in the shoes of those who left them out for him, a practice celebrated on his feast day, 6 December.
For those who still observe the Julian calendar the celebration currently takes place thirteen days later than it happens in the Gregorian calendar and Revised Julian calendar.

In Monaco, the Cathedral of Our Lady Immaculate was built from 1874 on the site of St Nicholas's church, founded in 1252.
A children's Mass is still held on 6 December in the cathedral.

In late medieval England, on Saint Nicholas Day parishes held Yuletide "boy bishop" celebrations.
As part of this celebration, youths performed the functions of priests and bishops, and exercised rule over their elders.
Today, Saint Nicholas is still celebrated as a great gift-giver in several Western European and Central European countries.
According to one source, in medieval times nuns used the night of 6 December to deposit baskets of food and clothes anonymously at the doorsteps of the needy.
According to another source, on 6 December every sailor or ex-sailor of the Low Countries (which at that time was virtually all of the male population) would descend to the harbour towns to participate in a church celebration for their patron saint.
On the way back they would stop at one of the various Nicholas fairs to buy some hard-to-come-by goods, gifts for their loved ones and invariably some little presents for their children.
While the real gifts would only be presented at Christmas, the little presents for the children were given right away, courtesy of Saint Nicholas.
This and his miracle of him resurrecting the three butchered children made Saint Nicholas a patron saint of children and later students as well.

Santa Claus evolved from Dutch traditions regarding Saint Nicholas (Sinterklaas).
When the Dutch established the colony of New Amsterdam, they brought the legend and traditions of Sinterklaas with them.
Howard G. Hageman, of New Brunswick Theological Seminary, maintains that the tradition of celebrating Sinterklaas in New York existed in the early settlements of the Hudson Valley, although by the early nineteenth century had fallen by the way.
St. Nicholas Park, located at the intersection of St. Nicholas Avenue and 127th Street, in an area originally settled by Dutch farmers, is named for St. Nicholas of Myra.
