In Hawaii the May Day is celebrated with the tradition of Lei. A festival of the natives of Hawaii, nurtured since time immemorial, Lei was officially celebrated first in 1929.

Though Lei is also thought to be in praise of the season of summer, it is celebrated in a very different way compared to the traditions associated with the European spring celebration.

The native islanders have some wonderful customs. They regard this day as a auspicious day. They greet the day with lei. A lei is a garland or necklace of flowers given in Hawaii as a token of welcome or farewell. Lei Day began in 1928.Leis are most commonly made of carnations, kika blossoms, ginger blossoms, jasmine blossoms, or orchids and are usually about 18 inches (46 cm) long.

Everyone gives the gift of a lei to another, putting it around the receiver's neck and accompanying it with the traditional kiss. Some Hawaiian celebrations are complete with pageants, a Lei Queen and her court.

While leaving the island a traveler customarily tosses the farewell lei onto the harbor waters. The drift of the lei back to the shore indicates that the person will someday return to the islands. The custom of wearing leis originated with the indigenous Hawaiians, who wove necklaces of leaves or ferns or sometimes strung dried shells, fruits, beads, or bright feathers for personal adornment. Hawaiians celebrate Lei Day on May 1, symbolizing their tradition of friendliness.
