The Birth of Baháʼu'lláh is one of nine holy days in the Baháʼí calendar, celebrated by Baháʼís and during which work is suspended. The holy day celebrates the birth of Baháʼu'lláh, the founder of the Baháʼí Faith; the 2017 date is October 22. Bahá'u'lláh was born on 12 November 1817 in Tehran and this holy day was instituted in the Kitáb-i-Aqdas, his book of laws, where Baháʼu'lláh first refers to four great festivals: the Festival of Ridván, the Declaration of the Báb, the birth of the Báb—who is considered to be a Manifestation of God, who foretold the coming of Baháʼu'lláh—and the birth of Baháʼu'lláh. In questions submitted to Baháʼu'lláh after writing the Kitáb-i-Aqdas, Baháʼu'lláh states that the two days commemorating the births of the Báb and Baháʼu'lláh are seen to be one in the "sight of God" and are referred to as the "Twin Birthdays".ʻAbdu'l-Bahá, the son of Baháʼu'lláh, stated that during the holy day the community should rejoice together to increase the unity of the community.
Baháʼís observe the holy day with community gatherings where prayers are shared and the birth of Baháʼu'lláh is celebrated. Baháʼu'lláh stated that in communities where the majority of the population are Shiʻa Muslims, such as Iran, his followers should exercise caution in celebrating the twin birthdays so that they do not upset the majority of the population who are mourning during the Islamic month of Muharram. In the Islamic calendar, a lunar calendar, the two holy days fall on consecutive days: the birth of the Báb is on the first day of Muharram in 1235 AH, the birth of Baháʼu'lláh is on the second day of Muharram in 1233 AH. Baháʼu'lláh stated that if the holy days occur during the Baháʼí month of fasting, Baháʼís need not observe the fast those days. Since the Baháʼí calendar is a solar calendar, the decision to celebrate the Twin Holy Birthdays in a solar or lunar basis remains to the Universal House of Justice; until March 20, 2015, in most of the world, the holy day was celebrated according to the solar year on 12 November, the birth of the Báb was celebrated on 20 October.
Since days in the Baháʼí calendar start at sunset, the holy day started on the evening of 11 November and proceeded until sunset on 12 November. However, in 2014, the Universal House of Justice decided to celebrate the twin holy days on the first and second day following the eighth new moon after Naw-Rúz, starting from March 20, 2015 onwards, thus from March 20, 2015 onward the day where the Birth of Baháʼu'lláh is celebrated will change from year to year.

Electronic Café International, established in 1988 by Kit Galloway and Sherrie Rabinowitz, is a performance space and real café housed in the 18th Street Arts Center in Santa Monica, California. The couple had realized after their experience with Electronic Café'84 that the next logical step was to establish a continuous venue for telepresence media events. For the next 10 years, the ECI lab was the site of electronic networking instigations that contributed to the canon of collaborative telecommunications arts. Phrases and terms such as'interactive dramaturgy,"metadesign environments,"telephone opera,"teleconcert,"tele-immersive,"telepresent' and'telepresence' emerged during 1989 to 2000, as the participating artists, their critics and theorists about their work attempted to describe and define the phenomena being created in the globally networked environment of Electronic Café International. ECI's broad-ranging programs included works such as localized celebrations of New Year's Eve or Earth Day expanded to global scale and extended 24 hours, when Electronic Café International and its affiliates in Europe, South America and Australia shared their celebrations with affiliated ECI patrons across the ECI network.
New music was composed for networked performance by composers such as Mark Coniglio, Max Mathews, Pauline Oliveros, David Rosenboom, Morton Subotnick. At ECI, poets and dramatic performance artists explored the attributes of telepresence. Since ECI opened in 1989, imitations of Galloway and Rabinowitz's concept of Electronic Café International have proliferated all over the planet
