The most unique Karvachauth holiday for married women is today, Thursday 

For the long life of her spouse 

a woman follows a Nirjala fast during this festival 

It has long been held that keeping this fast ensures 

the husband will live a long life and will have a happy marriage 

Married women follow the Nirjala Vrat 

a daylong fast without food or drink) on Karva Chauth, and they also worship Chauth Mata 

Only after offering her arghya and observing the moon in 

the night sky does she break her fast.
