What is the difference between the Isha calendar and the Indian national calendar?

The Isha calendar and the Indian national calendar serve different purposes and follow different systems.

1. Isha Calendar: The Isha calendar is associated with the Isha Foundation, founded by Sadhguru Jaggi Vasudev. This calendar is based on the positions of the sun and the moon and is designed to align with the natural cycles and rhythms of the human body and the planet. It might include specific timings for meditation, practices, or events based on these cosmic alignments. The Isha calendar often highlights auspicious timings for spiritual practices and rituals.

2. Indian National Calendar: The Indian national calendar, also known as the Saka calendar, is the official civil calendar in India. It was adopted by the Government of India in 1957 as the national calendar. This calendar is based on the traditional Hindu calendar and is a lunar calendar. It consists of 12 months, each corresponding roughly to a lunation. The months are calculated based on the position of the moon with respect to the sun.

The key difference lies in their purposes and foundations. The Isha calendar focuses on spiritual and cosmic alignments, often for practices and events associated with the teachings of the Isha Foundation. Meanwhile, the Indian national calendar is an official civil calendar used in India for administrative and civil purposes, rooted in traditional Hindu lunar calculations and used for various official and cultural events in the country
