A solar eclipse occurs when the Moon passes between Earth and the Sun, blocking some or all of the Sun’s visible disc for observers in particular locations. In India, a solar eclipse is also called Surya Grahan. Alongside the astronomical event, it has a place in religious stories, calendars and ritual traditions.

Those are related subjects, but they should not be confused. Astronomy explains the alignment of the Sun, Moon and Earth; cultural traditions explain how communities have understood and marked the occasion. This guide introduces both and shows where to check accurate dates and safe viewing information.

What causes a solar eclipse?

The Moon orbits Earth. Occasionally, at new moon, it lines up with the Sun from the viewpoint of a specific part of Earth. When its shadow falls on Earth, people in the affected region see an eclipse. The event does not appear across the whole planet at once.

Eclipses do not occur every month because the Moon’s orbit is tilted relative to Earth’s path around the Sun. Most new moons pass above or below the alignment needed for an eclipse.

What are the different types of solar eclipse?

The type and timing depend on your exact location. A solar eclipse described as “total” may be only partial—or not visible at all—from another city.

When are the next solar eclipses?

As of October 2026, the next two solar eclipses listed by NASA occur on 6 February 2027 and 2 August 2027. Their paths are different, and neither should be assumed to be visible from every part of India.

Check the NASA future eclipse calendar and its visibility maps before making viewing plans. Eclipse timings published in Universal Time may fall on a different local date for some viewers; do not rely on a date alone without a location.

Who is Surya in Indian religious and cultural traditions?

Surya is the Sun deity in Hindu traditions. The Sun appears in Vedic hymns and later religious literature and has long been associated with light, vitality, time and the daily rhythm of life. Different communities express that reverence in different ways—through prayer, temples, seasonal observances and personal practice.

In Hindu mythological accounts, the eclipse is often connected with the story of Rahu, sometimes together with Ketu. The story is a religious and symbolic explanation, not the astronomical cause of the Moon’s shadow crossing Earth. Teaching both accounts accurately means preserving their different purposes.

Why is the Sun honoured?

The Sun makes life on Earth possible through light and heat. Its apparent passage across the sky has shaped calendars, agricultural patterns and daily routines. Religious reverence for Surya gives those visible realities a devotional dimension.

Some people mark eclipse periods with prayer, fasting or bathing according to family and regional custom. Others simply observe the sky. There is no need to present one custom as a universal rule followed by all Indians.

How is Surya Namaskar related to Surya?

Surya Namaskar, often translated as Sun Salutation, is a sequence of physical movements coordinated with breathing. Its modern taught forms vary between yoga traditions. Some schools connect the movements with traditional names or mantras honouring Surya; others teach the sequence as physical practice.

Surya Namaskar can be practised at times other than sunrise and has no requirement to be performed during an eclipse. A person does not need to view the Sun directly to practise it. For physical safety, choose an appropriate pace and modify weight-bearing poses if wrists, shoulders or other joints need care.

How to watch a solar eclipse safely

Never look directly at the uneclipsed or partially eclipsed Sun without proper solar viewing protection. Ordinary sunglasses, even dark ones, are not safe. NASA advises using eclipse glasses or handheld viewers that meet recognised solar-viewing safety requirements for direct observation of a partial or annular eclipse.

During a total eclipse, only observers located within the path of totality may remove suitable eye protection for the short period when the Sun’s bright face is completely covered. Protection must be put back on immediately before any bright part becomes visible again. If you are uncertain whether you are in totality, keep the protection on.

Do not look through binoculars, a camera lens or a telescope without a properly fitted solar filter specifically designed for that equipment. Concentrated sunlight can cause serious eye injury. Review NASA’s eclipse safety guidance before attempting to observe one.

Are solar eclipses harmful to food, pregnancy or health?

An eclipse does not make food poisonous or cause an illness simply because the Moon temporarily covers the Sun. People may follow cultural precautions for personal religious reasons, but these should not be confused with proven medical risks.

The important direct physical risk associated with watching an eclipse is eye injury from unsafe exposure to sunlight. Anyone who is pregnant or has a medical condition should follow normal clinical guidance rather than treating an eclipse as a reason to stop prescribed care or avoid ordinary food.

Frequently asked questions about Surya Grahan

Is an eclipse the same as a new moon?

Solar eclipses occur at new moon, but most new moons do not produce a solar eclipse because the orbital paths are not closely enough aligned.

When is the next solar eclipse after October 2026?

NASA lists an annular solar eclipse on 6 February 2027. Where it will be visible depends on your location.

Are solar eclipses visible from all of India?

No. Each eclipse has its own geographic visibility path. Check a location-specific NASA map for the event.

Does Surya Namaskar need to be done during an eclipse?

No. It is a yoga practice taught in many formats and is not dependent on eclipse events.

What is the difference between Rahu and the astronomical explanation?

Rahu belongs to religious narratives and traditional astrology. Astronomically, the eclipse occurs when the Moon obstructs sunlight along a particular alignment.

The next time you hear about Surya Grahan, treat its science and its place in Indian culture as two subjects worth learning well. For related yoga philosophy, read our introduction to the Bhagavad Gita.
