2026 Ishti and Anvadhan dates are essential for devotees who follow traditional Vedic rituals, especially within the Vaishnava tradition. These observances are closely linked with Purnima (Shukla Paksha) and Amavasya (Krishna Paksha) and are performed in a strict sequence—Anvadhan first, followed by Ishti. This guide presents the complete and clearly arranged Ishti–Anvadhan calendar for 2026, along with their religious meaning, fasting rules, and ritual importance, based on widely accepted Panchang calculations for Ujjain, India.
What Are Ishti and Anvadhan?
Ishti and Anvadhan (इष्टि एवं अन्वाधान) are Vedic sacrificial observances described in the Shrauta and Smarta traditions.
- Anvadhan:
Observed one day before Ishti, it involves a day-long fast and preparatory rites. The sacred fire is ceremonially kindled, and mental as well as physical discipline is maintained. - Ishti:
Performed the next day, Ishti includes the actual Yajna (Vedic fire ritual), offerings to deities, and prayers for prosperity, purity, and spiritual balance.
Devotees strictly maintain this order—Anvadhan → Ishti—for ritual completeness.
Religious Significance of Ishti and Anvadhan Puja
- These rituals symbolize cosmic balance through fire (Agni).
- Observed mainly by Vaishnava followers, though respected across Sanatan traditions.
- The combination of fasting and Yajna represents self-control followed by divine offering.
- Traditionally associated with Purnima and Amavasya, enhancing their spiritual potency.
