Sovereign Discipline Calendar — Holy Days and Festivals

The Sikh tradition carries two calendar reckonings, and this order honours both. The Nanakshahi calendar (adopted 2003, revised 2010) is a tropical solar calendar with twelve fixed months — 1 Chet falling on 14 March, each month’s first day (Sangrand) fixed to the same Gregorian date every year. Before it, Sikh observance followed the Bikrami (Vikrami) lunisolar calendar, in which festival dates drift year to year; that lunar heritage is still how many traditionalists reckon certain holy days, notably Guru Nanak’s Gurpurb (Katak Puranmashi) and Bandi Chhor Divas (with Diwali). The SGPC follows the 2010 Nanakshahi for most fixed dates but retains lunar reckoning for three: Guru Nanak’s Gurpurb, Bandi Chhor Divas, and Hola Mohalla. Timing rules below give the Nanakshahi fixed date where the tradition states one, and note the lunar alternative where it is still observed.

Daily

• Amrit Vela (pre-dawn meditation) — Timing: the last quarter of the night, traditionally observed 3–6 AM; Nitnem Banis are recited between 2 and 6 AM. — The “ambrosial hours” of simran: the Sikh rises early to meditate on the Name (Naam simran) in stillness before the world stirs; this pre-dawn sitting is the crown of daily discipline.
• Nitnem — the Five Morning Banis — Timing: at Amrit Vela. The Sikh Rehat Maryada requires three — Japji Sahib (Guru Nanak’s opening meditation), Jaap Sahib (Guru Gobind Singh’s praise of the Timeless), and the Ten Savaiye (Tav-Prasad Savaiye) — while the widespread practice adds Chaupai Sahib and Anand Sahib for the full five, followed by Ardas. — Kept by recitation from a gutka (prayer book), individually or in gurdwara congregation.
• Rehras Sahib (evening prayer) — Timing: at sunset. — Composed of hymns by Guru Nanak, Guru Ram Das, and Guru Arjan Dev, with compositions of Guru Gobind Singh (Benti Chaupai, “Pae gahe jab te tumre,” “Sagal duar kau chhad kai”) and portions of Anand Sahib; followed by Ardas.
• Kirtan Sohila (night prayer) — Timing: last thing before sleep. — Five compositions by Guru Nanak, Guru Ram Das, and Guru Arjan Dev from the Guru Granth Sahib, sung or recited to close the day.

Weekly

• Weekly diwan (gurdwara congregation) — Timing: Sundays in the diaspora; in Punjab and at major shrines, diwans occur daily. — The sangat gathers for Gurbani kirtan (devotional music), katha (exposition), the reading of the Hukamnama, and langar (community meal); in Western countries the main congregation traditionally meets on Sunday.

Monthly

• Sangrand — Timing: the first day of each Nanakshahi month, fixed to the same Gregorian date each year (Chet 14 March, Vaisakh 14 April, Jeth 15 May, Harh 15 June, Sawan 16 July, Bhadon 16 August, Assu 15 September, Katak 15 October, Maghar 14 November, Poh 14 December, Magh 13 January, Phaggan 12 February). — Traditionally reckoned by the Bikrami solar ingress into each rashi; kept with an early-morning diwan, kirtan, and reading of the corresponding month’s hymn from the Guru Granth Sahib.
• Puranmashi (full moon) — Timing: the full-moon day of each Bikrami lunar month — the one observance reckoned by lunar reckoning even under Nanakshahi adoption. — A day of special diwan and kirtan in the gurdwara; the full moon of Katak (October–November) is the largest, as it marks Guru Nanak’s Gurpurb.

Quarterly

• There is no distinct quarterly rhythm in Sikh observance. The monthly Sangrand and Puranmashi, together with the annual Gurpurbs and the seasonal fairs (Vaisakhi, Hola Mohalla), carry the year; no tradition of quarterly holy days is attested.

Yearly

• Vaisakhi (Khalsa Sajna Divas) — Timing: 1 Vaisakh, fixed at 14 April (Nanakshahi and Mool Nanakshahi agree). — The founding of the Khalsa (1699) by Guru Gobind Singh: kept with Nagar Kirtan processions, Amrit Sanchar (initiation), kirtan, and the reading of the Khalsa’s founding history.
• Hola Mohalla — Timing: 1 Chet, 14 March per Mool Nanakshahi; SGPC observes it on the Bikrami lunar date (the day after Holi, drifting in March). — Guru Gobind Singh’s alternative to Holi (1701): kept with martial arts displays (gatka), mock battles, and kirtan, especially at Anandpur Sahib.
• Guru Nanak’s Gurpurb (Parkash Divas) — Timing: Katak Puranmashi (full moon of Katak, October–November, drifting) per the dominant Bikrami tradition; Mool Nanakshahi fixes it at 14 April (1 Vaisakh). — The birth of Guru Nanak: three days of celebration — Akhand Path (48-hour continuous reading of the Guru Granth Sahib) begins two days prior, a Nagar Kirtan procession the day before, and the main day of kirtan, fireworks, and lights.
• Guru Gobind Singh’s Gurpurb (Parkash Divas) — Timing: 23 Poh, 5 January (fixed, Nanakshahi). — Birth of the tenth Guru, founder of the Khalsa: kept with Akhand Path, kirtan, and narration of his life.
• Guru Arjan Dev’s Shaheedi (martyrdom) — Timing: 2 Harh, 16 June (fixed, Nanakshahi). — Commemoration of the fifth Guru’s martyrdom in Lahore (1606): observed solemnly with kirtan and history; chhabeel (sweet water) is traditionally served.
• Guru Tegh Bahadur’s Shaheedi (martyrdom) — Timing: 11 Maghar, 24 November (fixed, Nanakshahi). — Commemoration of the ninth Guru’s martyrdom in Delhi (1675): solemn diwans and remembrance of his stand for freedom of conscience.
• Bandi Chhor Divas — Timing: Mool Nanakshahi fixes it at 12 February (1 Phaggan); SGPC and the dominant tradition observe it with Diwali (Bikrami lunar date, October–November). — The release of Guru Hargobind from Gwalior Fort (1619) with 52 captive princes: kept with diva-lighting, illuminations at Harmandir Sahib, and diwans.
• Gurgaddi of the Guru Granth Sahib — Timing: 6 Katak, 20 October (fixed, Nanakshahi). — The conferral of eternal guruship on the scripture (1708): commemorated in diwan with kirtan.
• First Parkash of the Guru Granth Sahib (installation at Harmandir Sahib) — Timing: 17 Bhadon, 1 September (fixed, Nanakshahi). — The scripture’s first installation (1604): kept with Akhand Path and kirtan.

Uncertainties for owner review

1. Guru Nanak’s Gurpurb date: this is genuinely contested. Mool Nanakshahi fixes it at 14 April (1 Vaisakh), but the dominant worldwide observance remains Katak Puranmashi (October–November). I present the lunar reckoning as the lived majority practice and note the Mool position; the owner should decide which the order endorses.
2. Bandi Chhor Divas date: same split — 12 February (Mool Nanakshahi) vs. Diwali (dominant lunar tradition). Presented with both.
3. Hola Mohalla date: 14 March (Mool Nanakshahi) vs. the day after Holi on the Bikrami lunar calendar (SGPC). Presented with both.
4. The Five Banis: the Sikh Rehat Maryada strictly requires only three morning Banis (Japji Sahib, Jaap Sahib, the Ten Savaiye); Chaupai Sahib and Anand Sahib are near-universal additions but not obligatory per the code. I noted this distinction in the Daily section.
5. Amrit Vela is commonly glossed as 3–6 AM; some sources place the Nitnem window at 2–6 AM. The description covers both.
6. Smaller sectarian festivals (e.g., Ravidas Jayanti in Ravidassia observance) were omitted as they belong to specific sampardayas rather than the shared Sovereign Discipline tradition; add if the owner wishes.
