Pournami and night Girivalam

How the full-moon window works

Girivalam is traditionally done while the Pournami tithi is in effect. A tithi is a lunar day, and it rarely begins at midnight. It lasts roughly a day and usually spans two calendar dates, starting on one day and ending on the next. That’s why Girivalam dates are often quoted as two days. The blog post Why Girivalam dates span two days explains the astronomy.

Our Pournami calendar lists the start and end of every full-moon tithi for 2026–2028 in Indian Standard Time. The times are calculated and match published Girivalam calendars; the next one is shown above.

What the night walk is like

On a full-moon night the road becomes a slow river of people. There are families with children, groups chanting Om Namah Shivaya, sadhus, and first-timers who have travelled from Chennai or Bengaluru. Stalls sell tea, snacks, flowers and camphor, and devotee groups often hand out water and food. The street lighting on the Girivalam road makes the walk manageable at night, and the moon over the hill is a sight in itself.

Crowds and road closures

• Traffic: on Pournami the Girivalam road and roads near the temple are closed to most vehicles. Special buses and parking areas are set up on the edge of town, so allow extra time to reach the start.
• Darshan: queues at the temple are long through the night.
• Accommodation: rooms near the temple and on the route sell out on full-moon weekends; see where to stay.
• Busiest full moons: Karthigai Pournami (Karthigai Deepam) and Chithirai Pournami (April–May). The district administration also names the first day of each Tamil month and Tamil New Year as days when pilgrims walk.

Night-walking safety

• Walk with company, especially on ordinary nights when some stretches are quiet.
• Carry a small torch, water, and a little cash in a front pocket.
• Agree a meeting point in case your group gets separated in the crowds.
• Keep children close, and write your phone number on a card in their pocket.
• If you feel unwell, step off the road and rest. Autos wait at many points on Pournami.

If you prefer a quiet walk

Walk on an ordinary weekday morning, or a day or two after the full moon. You’ll share the road with a few regular walkers and have time to stop at every lingam. See first-time Girivalam for a checklist.
