Sikh history, fully sourced. Open to all

Sikh festivals are not celebrations of mythology — they are commemorations of real events and real people. Every Gurpurab marks a moment already covered on the History & Timeline pages of this portal: a birth, a martyrdom, a founding. Reading them alongside the timeline makes both richer. This page is a practical guide to what each festival marks, why it matters, and how it's observed.
Sikh festivals follow the Nanakshahi Calendar, formally launched by the SGPC on 14 April 2003 at Takht Sri Damdama Sahib, based on the solar year rather than a lunar cycle. It was designed to give Sikh observances fixed dates on the Gregorian calendar, making Gurpurabs easier to plan globally. Some dates remain subject to ongoing discussion within Sikh governance bodies — several major Gurpurabs, including Guru Nanak's birthday and Bandi Chhor Divas, are still observed on the traditional lunar (Bikrami) dates rather than the fixed solar ones. This portal notes both where relevant.
What it marks: The founding of the Khalsa by Guru Gobind Singh at Anandpur Sahib on 13 April 1699 — the single most consequential day in Sikh institutional history.
On this day in 1699, Guru Gobind Singh issued a call for five volunteers willing to give their lives for the faith. The five who came forward — the Panj Pyare — were initiated into the Khalsa and became the model for all subsequent initiations. The day is also the traditional harvest festival of Punjab, giving it both spiritual and agricultural roots.
How it's observed: Nagar Kirtan (a procession through the streets with the Guru Granth Sahib carried at its centre), Amrit Sanchar ceremonies at Gurdwaras, communal Langar and celebration. In diaspora communities including Australia, Nagar Kirtan draws Sikh and non-Sikh participants alike.
What it marks: The birth of the founder of Sikhism, 15 April 1469 at Nankana Sahib (now Pakistan) — the largest Gurpurab of the year. This is the solar calendar birth date; the Gurpurab itself is observed in November, following the traditional lunar Kattak date, since this is one of the Gurpurabs the SGPC kept on the movable lunar calendar.
How it's observed: A 48-hour Akhand Path (continuous reading of the Guru Granth Sahib) concludes before dawn on the day itself, followed by Kirtan, Langar, and Nagar Kirtan. Nankana Sahib draws hundreds of thousands of pilgrims for this occasion, with the Kartarpur Corridor (opened 2019) offering a partial route for Indian Sikhs to honour the connected sites.
What it marks: The release of Guru Hargobind Ji from Gwalior Fort in 1619, where he had been imprisoned by Emperor Jahangir. He refused release unless 52 Hindu kings imprisoned alongside him were freed at the same time, insisting they each hold a cord of his cloak as he walked out — ensuring all 52 could exit simultaneously.
How it's observed: Gurdwaras are illuminated with lights; fireworks are common in many communities. The festival often overlaps with the Hindu festival of Diwali, and the two are sometimes conflated — the distinction matters: Bandi Chhor Divas has its own specific Sikh historical meaning.
What it marks: Established by Guru Gobind Singh at Anandpur Sahib as a Sikh alternative to the Hindu festival of Holi — shifting the emphasis from colour-play to martial arts demonstrations, poetry, and music.
How it's observed: At Anandpur Sahib, the three-day festival features Gatka (Sikh martial arts) demonstrations, mock battles on horseback, Kirtan competitions, and large-scale Langar — one of the most visually dramatic events in the Sikh calendar.
What it marks: The execution of the fifth Guru in 1606 in Lahore — the first great martyrdom in Sikh history (Shaheedan-de-Sartaj, "Crown of Martyrs").
How it's observed: Sikhs gather at Gurdwaras for Kirtan and prayer. In Amritsar and Lahore, communities set up stalls serving cold sharbat (sweet drinks) to passers-by — a public act of Sewa recalling how ordinary people offered water to Guru Arjan as he was walked through the streets in June's summer heat.
What it marks: The execution of the ninth Guru in 1675 in Delhi, martyred for defending the right of Kashmiri Pandits — who were not Sikh — to practise their own faith freely. A martyrdom for the protection of religious freedom generally, not only for Sikhism.
How it's observed: Kirtan, prayers, and remembrance at Gurdwara Sis Ganj Sahib in Chandni Chowk, Delhi — the site of the execution — and at Gurdwaras globally.
