fasts and vrats
What is Pradosh vrat and how is it different from Shivaratri?
What each vrat is
Pradosh vrat is observed on the 13th lunar day, called trayodashi. It is done in the evening, usually at sunset or in the hours just before dark. The fast is meant to honor Shiva and is believed to bring peace and remove obstacles. Shivaratri is observed on the 14th lunar day, called chaturdashi, and is kept through the night. It is seen as a more intense fast, with many people staying awake to pray and chant. Both come from the Shiva Purana and are part of the tradition of honoring Shiva.
When they fall
Both vrats happen twice a month, once in the dark fortnight and once in the bright fortnight. Because Pradosh is on the 13th and Shivaratri is on the 14th, they fall on consecutive days. This means both can be observed in the same fortnight. Some people do Pradosh one day and Shivaratri the next. Others choose one or the other, or do both in different months. The choice depends on the person's practice and what their family tradition holds.
In practice today
Many people observe Pradosh as a shorter, evening fast that fits into a busy day. Shivaratri, being a full night, asks for more time and is often marked as a bigger occasion. Some households do both when they fall close together, while others focus on one. The practice varies by region, family, and personal choice. Both are still widely kept in India and by Hindus around the world.
