The Chhath devotees have been observing fasting since early morning and now preparing to offer arghya (curd and holy water) to the setting sun later this evening.

Observance of fasting is a significant part of the Chhath festival. However, only devotees and not all celebrants observe the rigorous fasting during which they have to abstain even a drop of water.

The Sun God, Chhathi Mata and rivers are worshipped during this festival. The offering of the curd is conducted on the sixth day of the bright fortnight in the month of Kartik. The curd is offered by adhering to the rituals. 

On the main day of the Chhath today, there is a bustling presence of celebrants and devotees from Guheshwori to Gaurighat- the Bagmati River bank above the Pashupatinath Temple- in Kathmandu. 

The mythological belief has it that Draupadi had worshipped the Sun God and wished success to the five Pandavas when their whereabouts was not clear. The holy text, Mahabharat, has such mention. It is believed the celebration of the Chhath festival began then.

Similarly, the Surya Purana has explained it was Anushuya, spouse of Atrimuni, observing the Chhath fasting, which resulted in happiness and love and fulfilling life with the spouse. The Surya Purana believes it is the beginning of the Chhath festival which continues thereafter.

As part of the festival, the devout abstain from meals for once since the fourth day of bright fortnight, while observing the rigorous fasting later. Similarly, the offering with fruits and pudding is made to Shasthi Mata on the sixth day.

The Guheshwori Gaurighat Chhath Puja Committee informed that the devotees who have observed rigorous fasting are offering arghya to the setting sun this evening.  

Kamalpokhari, Nakkhu and Bishnumati river banks are also decorated for Chhath celebration. 

The Chhath festival, initially limited to the Mithila region, expanded gradually to other Tarai districts and hills including the federal capital, Kathmandu, in recent years.

The President, Vice President and other dignitaries have extended best wishes to all Nepali sisters and brothers on this occasion. 

The government has given a public holiday for the Chhath celebration today. 

It is the festival of cleanliness, purity, worship to nature and Sun God, family bond and harmony in community.
