Besides the Kumbh there are half- way congregations at these cities. These are called the Ardhakumbh.
Unlike the Kumbh, during the Ardhakumbh, the sadhus move to Ujjain with their Akharas.
The Simhastha Kumbhs at Nashik and Ujjain generally fall at a year's interval. At both these places the sadhus and the commoners get together, making these fairs a meeting ground of those who have renounced the world.
