What are the 6 time cycles according to Jainism, names & brief differentiation

In Jain cosmology, time is eternal and divided into infinite cycles called Kālacakra, each consisting of two halves: Utsarpiṇī (ascending) and Avasarpiṇī (descending). Each half-cycle is further divided into six smaller time cycles characterized by varying degrees of happiness, lifespan, and morality. The six time cycles are named as follows: 1) Suṣama Suṣamā (extremely happy), 2) Suṣamā (happy), 3) Suṣama Dūṣamā (happy and unhappy), 4) Dūṣama Suṣamā (unhappy and happy), 5) Dūṣamā (unhappy), and 6) Dūṣama Dūṣamā (extremely unhappy). These cycles reflect the gradual rise or decline in spiritual and moral conditions of beings. In the Utsarpiṇī phase, conditions improve progressively through these six stages, whereas in the Avasarpiṇī phase, conditions deteriorate through the same stages in reverse order. This cyclical framework explains the ebb and flow of dharma, lifespan, and human virtues over cosmic time.
