Dates & important timings
According to the panchang, Purnima tithi begins at 10:36 PM on November 4, 2025, and ends at 06:48 PM on November 5, 2025. Because the Purnima falls across the night, most communities observe festivals on November 5.
For Dev Diwali (Varanasi): the traditional Pradosh muhurat — considered best for diya lighting and Ganga aarti — is observed in the evening hours (around 05:15 PM to 07:50 PM). These timings are used widely by media and regional panchangs for 2025 celebrations. (See regional coverage for local variations.)
Guru Nanak Jayanti commemorates the birth of Guru Nanak Dev Ji, the founder of Sikhism, whose teachings emphasise equality, service and remembrance of one God. On Gurpurab, gurdwaras organise early morning akhanda paath, langar (community kitchen), and nagar kirtans processions carrying the Guru Granth Sahib. Devotees join congregational prayers (ardas) and perform sewa (voluntary service) at gurdwaras across India and the world. (Read more background in mainstream coverage.)
Dev Diwali why Varanasi lights up
Dev Diwali — literally ‘Diwali of the gods’ is celebrated on Kartik Purnima when, by tradition, deities are said to descend to the ghats. Varanasi and major ghat cities like Haridwar and Rishikesh mark the night with thousands of diyas along the river, special Ganga aarti ceremonies, cultural shows and mass diya-floating. City administrations often plan large public arrangements crowd control, sanitation and lighting to manage the inflow of devotees.
How people celebrate practical tips
Gurudwaras: Attend langar, follow etiquette, and plan travel early. Expect longer queues on Gurpurab.
Ghats & aarti: If visiting Varanasi, arrive before evening aarti; municipal schedules can change check local announcements and respect safety ropes and barriers.
Environmental note: Many organisers encourage eco-friendly diyas and avoid plastic decorations near the river.
State observances and public holidays
Guru Nanak Jayanti is a public holiday in several Indian states; banks and some offices may be closed in regions with large Sikh populations. Schools in affected states may issue holiday notices in advance. Check local government and bank holiday lists for state-wise closures.
