Chhath Puja 2026: Why Is Chhath Celebrated? Learn About Its Religious and Scientific Significance

Introduction: Why Is Chhath Puja Celebrated?

India has countless festivals, but some celebrations have a special connection with nature. Chhath Puja is one such festival. It is not just about prayers, fasting or religious traditions. It is also about expressing gratitude to the natural elements that make life possible.

Celebrated with immense devotion, especially in Bihar, Jharkhand, eastern Uttar Pradesh and Nepal, Chhath Puja is dedicated to Lord Surya (the Sun God) and Chhathi Maiya. During this festival, devotees offer prayers to both the setting and rising sun, observe strict fasts and follow traditional rituals that have been passed down through generations.

But have you ever wondered why the Sun is worshipped during Chhath Puja? Why do devotees offer Arghya to the setting sun instead of worshipping only the rising sun? Is there any scientific significance behind standing in water, fasting and performing prayers during sunrise and sunset?

These questions make Chhath Puja even more interesting.

In 2026, Chhath Puja will be celebrated from November 13 to November 16. As families prepare for this sacred occasion, let's understand why Chhath is celebrated, what religious beliefs are associated with it and how its traditions connect with science and the natural world.

Chhath Puja 2026: Important Dates

Before exploring the religious and scientific significance, here is the four-day Chhath Puja schedule for 2026.

The festival concludes after devotees offer prayers to the rising Sun on the morning of November 16.

What Is Chhath Puja?

Chhath Puja is an ancient Hindu festival dedicated primarily to the worship of the Sun God, also known as Surya Dev, and Chhathi Maiya, who is associated with Shashthi Devi.

The word 'Chhath' is commonly associated with the sixth day of the lunar fortnight. The principal observance takes place on Kartik Shukla Shashthi, although the complete celebration lasts four days.

Unlike festivals where worship is performed mainly inside temples, Chhath Puja is traditionally celebrated in open spaces, particularly near rivers, ponds, lakes and other water bodies.

Devotees prepare traditional offerings, observe fasting and gather at Chhath ghats to offer Arghya to the Sun.

The festival is especially known for its strict discipline. Many devotees observe a demanding Nirjala fast, traditionally avoiding both food and water for approximately 36 hours after Kharna.

For many families, Chhath Puja is more than an annual religious event. It is an important part of their identity, culture and family traditions.

Why Is Chhath Puja Celebrated? Religious Significance

The religious significance of Chhath Puja is closely connected with the belief that the Sun is the source of life, energy, health and prosperity.

In Hinduism, Lord Surya is considered one of the most important natural deities. The Sun provides light, supports agriculture and represents vitality and positive energy.

Devotees worship Surya Dev to express gratitude and seek blessings for the well-being of their families.

Let's understand the major religious beliefs associated with this festival.

1. Worship of Lord Surya: The Source of Life

The most important reason behind celebrating Chhath Puja is the worship of Lord Surya.

In Hindu religious traditions, the Sun is regarded as a powerful deity who sustains life on Earth. Ancient Vedic hymns also contain prayers dedicated to the Sun and its life-giving energy.

Devotees believe that worshipping Surya Dev brings good health, strength, prosperity and positive energy into their lives.

The Sun is also associated with truth, discipline, knowledge and the removal of darkness.

During Chhath Puja, devotees offer water, milk, fruits and traditional prasad to express their gratitude to the Sun God.

For them, this is not simply a ritual. It is a way of acknowledging the importance of something that supports every living being, regardless of religion, region or social background.

2. Worship of Chhathi Maiya for Children's Well-Being

Another important part of Chhath Puja is the worship of Chhathi Maiya.

She is commonly associated with Shashthi Devi, a goddess connected with the protection of children and family welfare in Hindu traditions.

Devotees believe that Chhathi Maiya blesses families with happiness, prosperity and the well-being of their children.

Many parents observe Chhath Puja to pray for their children's good health, long life and bright future. Some devotees also undertake the fast to fulfil religious vows or express gratitude for blessings they believe they have received.

The emotional connection between Chhathi Maiya and family life makes this festival particularly meaningful for parents and families.

3. Gratitude Towards Nature

Chhath Puja teaches one of the simplest yet most meaningful lessons: never take nature for granted.

The Sun, water, air, soil and plants are essential for human survival. Without these natural resources, life as we know it would not exist.

The festival brings this connection into everyday religious practice.

Devotees worship the Sun while standing in water, offer seasonal fruits and traditional agricultural produce, and gather near natural water bodies.

This connection with nature is one of the reasons Chhath Puja holds such a special place in Indian culture.

4. Respect for Both the Rising and Setting Sun

One of the most unique traditions of Chhath Puja is that devotees worship both the setting and rising sun.

On the third day, they offer Sandhya Arghya to the setting sun. On the fourth day, they offer Usha Arghya to the rising sun.

This tradition carries a beautiful spiritual message.

The setting sun represents the completion of a day, while the rising sun represents hope and a fresh beginning.

By offering prayers to both, devotees express gratitude throughout the natural cycle of life.

It also reminds us that every stage of life deserves respect, whether it represents growth, achievement, change or an ending.

Religious Stories and Mythological Beliefs Behind Chhath Puja

Several stories from Hindu mythology are associated with Sun worship and the traditions of Chhath Puja. These stories help explain why devotees consider the festival so sacred.

It is important to understand that different regions and families may follow different versions of these traditional accounts.

1. The Story of Lord Rama and Goddess Sita

According to a popular religious tradition, Lord Rama and Goddess Sita worshipped the Sun God after returning to Ayodhya following their victory over Ravana.

It is believed that they observed a fast and performed Sun worship to express their devotion.

This story is often associated with the religious importance of Chhath Puja and the tradition of offering prayers to Surya Dev.

2. The Story of Draupadi and the Pandavas

Another popular story comes from the Mahabharata.

According to a traditional account, Draupadi faced difficulties during the Pandavas' period of exile. She sought guidance from a sage, who advised her to worship the Sun God and observe a fast.

It is believed that her devotion helped the Pandavas overcome their difficulties.

This story is remembered by many devotees as an example of faith, patience and the power of prayer.

3. Karna's Devotion to the Sun God

Karna, one of the most respected characters in the Mahabharata, was the son of Surya Dev.

According to the epic tradition, Karna worshipped the Sun God with great devotion. He is often associated with generosity, courage and discipline.

His connection with Surya Dev is one reason why the Sun holds such an important place in Mahabharata-related stories about Sun worship.

These mythological accounts are part of the cultural and religious heritage surrounding Chhath. They are traditionally understood as stories of devotion rather than modern historical records.

Scientific Significance of Chhath Puja

Apart from its religious importance, Chhath Puja has several interesting connections with nature, environmental awareness and human behaviour.

Some aspects of the festival can be understood through established scientific principles. However, it is important not to confuse cultural traditions with medical treatments or scientifically proven health benefits.

Let's explore some of these connections.

1. The Sun Is Essential for Life on Earth

The most obvious scientific connection is the importance of sunlight.

The Sun is the primary source of energy for most life on Earth. Plants use sunlight during photosynthesis to produce food, which supports the food chain.

Sunlight also helps regulate natural day-and-night cycles and influences the Earth's climate.

For human beings, exposure to sunlight helps the skin produce vitamin D, which plays an important role in maintaining healthy bones and supporting normal body functions.

However, excessive exposure to ultraviolet radiation can damage the skin and eyes. Safe exposure depends on factors such as location, season, skin type and time spent outdoors.

Chhath Puja's focus on the Sun can therefore be understood as a powerful cultural expression of gratitude towards an essential source of life.

2. Why Are Both Sunrise and Sunset Important?

Chhath Puja gives special importance to the two daily transitions between daylight and darkness.

Scientifically, sunrise and sunset are important parts of the natural light-dark cycle that helps regulate the human body's circadian rhythm.

The circadian rhythm is the body's internal timing system. It influences sleep, alertness, hormone release and several other biological processes.

Morning light, in particular, helps the body maintain its natural sleep-wake cycle.

The festival's early morning gathering offers devotees an opportunity to experience the natural environment at sunrise.

However, there is no established scientific evidence that offering Arghya itself provides special medical benefits or that sunset and sunrise prayers cure diseases.

The religious meaning of these rituals remains distinct from their scientific explanation.

3. The Importance of Fasting and Self-Discipline

Fasting is one of the most demanding parts of Chhath Puja.

After completing Kharna, many devotees observe a strict Nirjala fast that traditionally lasts approximately 36 hours.

From a scientific perspective, fasting changes the way the body uses available energy. During periods without food, the body gradually shifts from using recently consumed nutrients towards stored energy sources.

Some forms of intermittent fasting have been studied for their possible effects on metabolism and other health markers.

However, this does not mean that the prolonged, water-free fast observed during Chhath is medically beneficial or safe for everyone.

Dehydration and low blood sugar can cause weakness, dizziness and other health problems. A strict Nirjala fast can be particularly risky for people with medical conditions, pregnant individuals, children and older adults.

The religious value of fasting is based on devotion and self-discipline, not on a medical requirement.

Anyone considering a prolonged fast should discuss its safety with a qualified healthcare professional.

4. Standing in Water During Arghya

During Sandhya Arghya and Usha Arghya, devotees traditionally stand in rivers, ponds or other water bodies while offering prayers to the Sun.

Water has always been an important part of human civilisation. Rivers and ponds support agriculture, provide drinking water and sustain many forms of life.

The use of water in Chhath rituals highlights its cultural and spiritual importance.

From a practical perspective, gathering near water bodies also creates an opportunity to bring communities together for maintaining and cleaning public spaces.

However, standing in water does not have a proven special healing effect. Water quality and personal safety matter, particularly in crowded areas or polluted water bodies.

5. Cleanliness and Environmental Awareness

One of the most meaningful aspects of Chhath Puja is the importance given to cleanliness.

Before the festival, devotees clean their homes, kitchens and surroundings. Communities also make efforts to clean riverbanks, ponds and Chhath ghats.

This tradition has an important environmental message.

Clean rivers and ponds are essential for public health, agriculture, biodiversity and the availability of safe water.

The traditional use of bamboo baskets, natural offerings and locally sourced ingredients also reflects a close connection with local materials and agricultural life.

Modern celebrations can strengthen this environmental message by:

Avoiding plastic decorations and disposable items.

Keeping rivers and ponds free from waste.

Using natural or reusable decorations.

Disposing of flowers and organic offerings responsibly.

Avoiding chemical colours and harmful materials near water bodies.

Participating in community cleanliness activities.

The festival becomes even more meaningful when devotion is accompanied by genuine care for the environment.

6. The Scientific Importance of Seasonal Fruits and Traditional Food

Chhath Puja offerings commonly include bananas, coconuts, sugarcane, seasonal fruits and traditional homemade sweets.

These foods reflect the agricultural traditions and seasonal produce of the regions where the festival is celebrated.

Fruits provide different vitamins, minerals, dietary fibre and natural carbohydrates. Bananas, for example, contain potassium and vitamin B6.

Traditional preparations such as thekua and jaggery-based kheer also represent regional food culture and family heritage.

However, religious offerings should not automatically be described as medicinal foods. Their nutritional value depends on ingredients, preparation methods and portion sizes.

The main significance of these offerings is their place in the religious and cultural traditions of Chhath Puja.

Why Is Chhath Puja Called an Eco-Friendly Festival?

Chhath Puja is often associated with nature-friendly traditions because its rituals revolve around natural elements.

The festival brings together the Sun, water, fruits, agricultural produce, flowers and other materials that are closely connected with the environment.

Unlike many celebrations centred on elaborate decorations, traditional Chhath rituals are relatively simple.

Some important environmentally conscious aspects include:

Worship of natural elements: Devotees express gratitude towards the Sun and water, two essential resources for life.

Use of bamboo baskets: Traditional Soop and Daura are commonly made from bamboo and other natural materials.

Seasonal offerings: Fruits and agricultural produce form an important part of the offerings.

Community cleanliness: Families and local communities often participate in cleaning Chhath ghats and nearby surroundings.

Respect for water bodies: Rivers, ponds and lakes hold a central place in the festival's rituals.

Of course, no festival is automatically pollution-free. Large gatherings can create waste, and poorly managed offerings may harm water bodies.

That is why environmentally responsible celebrations are important.

Why Is Chhath Puja So Popular in Bihar and Eastern Uttar Pradesh?

Chhath Puja has a particularly strong cultural connection with Bihar, Jharkhand and eastern Uttar Pradesh.

For generations, families in these regions have celebrated the festival with devotion and have passed its traditions from one generation to the next.

The festival is deeply connected with local agriculture, folk music, traditional food and family relationships.

Chhath songs are especially important. Many traditional songs describe the devotion of mothers, the blessings of Chhathi Maiya and the beauty of offering prayers to the rising and setting sun.

For people who have moved away from their hometowns, Chhath is also an emotional connection to their roots.

Whether celebrated in Patna, Ranchi, Delhi, Mumbai or abroad, the festival brings people together and helps preserve cultural identity.

The Social Significance of Chhath Puja

Chhath Puja is not celebrated by one family alone. It involves the participation of entire neighbourhoods and communities.

Families prepare prasad together, arrange offerings, decorate their homes and help each other with festival preparations.

At Chhath ghats, people from different social and economic backgrounds gather to offer prayers.

The festival encourages several important social values:

Unity: Community members work together to organise the celebrations.

Equality: Devotees gather at the same water bodies and participate in shared rituals.

Family bonding: The festival brings relatives together and strengthens family relationships.

Cultural preservation: Traditional songs, recipes and customs are passed down through generations.

Service and cooperation: People volunteer to clean ghats, arrange facilities and help other devotees.

These values make Chhath Puja an important cultural celebration beyond its religious meaning.

The Four Days of Chhath Puja and Their Deeper Meaning

Each day of Chhath Puja represents a different aspect of devotion and preparation.

From cleaning the home to offering prayers at sunrise, the festival follows a meaningful sequence that combines personal discipline, family participation and respect for nature.

What Can We Learn From Chhath Puja in Modern Life?

Chhath Puja carries lessons that remain relevant even for people who do not observe the fast.

Its message goes beyond religious boundaries.

Here are some values that everyone can take from the festival:

Be grateful: Appreciate the natural resources that support everyday life.

Respect nature: Protect rivers, ponds, trees and other natural resources.

Value family: Spend meaningful time with loved ones.

Practise discipline: Develop patience and commitment in everyday activities.

Help others: Participate in community activities and support those around you.

Respect every stage of life: Learn to appreciate both beginnings and endings.

Preserve traditions: Keep cultural heritage alive by sharing it with younger generations.

In a world where people are often busy with their daily routines, Chhath Puja provides a reminder to pause, reflect and reconnect with nature and family.

Conclusion: Chhath Puja Is a Celebration of Faith, Nature and Life

Chhath Puja is much more than a traditional Hindu festival. It is a beautiful combination of religious devotion, cultural heritage, family values and respect for nature.

Devotees celebrate it to worship Lord Surya and Chhathi Maiya, seek blessings for their families and express gratitude for the natural forces that sustain life.

Its scientific connections are equally interesting. The Sun supports life, morning light influences the body's internal clock, water is essential for healthy ecosystems, and cleanliness plays an important role in protecting public health.

At the same time, it is important to recognise that religious fasting and rituals should not be presented as proven medical treatments. Devotion and science can be discussed together without making unsupported health claims.

In 2026, as devotees gather at rivers, ponds and Chhath ghats from November 13 to November 16, the festival will once again bring families and communities together.

Perhaps the greatest lesson of Chhath Puja is a simple one: life is a gift, nature deserves our respect, and gratitude should be part of our everyday lives.

May Lord Surya and Chhathi Maiya bless everyone with good health, happiness, peace and prosperity.

Wishing you and your family a blessed Chhath Puja 2026! Jai Chhathi Maiya! Jai Surya Dev!
