Arunachala Pournami Full Moon and Sivaratri GiriValam Dates and Timings Read the following articles to learn about Arunachala and GiriValam. 1. ARUNACHALA Wisdom of the Agasthiar Siddha Lineage 2. How to do Arunachala Girivalam according to the Siddha Way 3. Basic Girivalam Rules 4. The Great Karthigai Deepam Festival in Arunachala (Thiru Annamalai). 5. Lots of Articles. As we have mentioned before, those who cannot be in Arunachala at the times shown below can do Giri Valam around other sacred hills such as Thiruparankundram, Thidiyan Malai, Karur Thaanthondrimalai, Palani, Trichy RockFort, Rathnagiri Aiyarmalai, Kundrakudi, Thirukachoor (near Madras), Thirukazhukundram, Parvatha Malai, etc.

Sivaratri occurs every month. More precisely, as Sathguru Venkataraman pointed out, Shivaratri occurs every night (Nitya Shivaratri), every fortnight (Paksha Sivaratri), every month (Maasa Sivarathri) and every year (Maha Sivarathiri).
Monthly Sivaratri GiriValam - on the night preceding the New Moon Night. Monthly Pournami GiriValam - on the night of the Full Moon.
