The name of a certain kind of kalpa that literally means “incalculable.” The number of years in this kalpa differs in the various sūtras that give it a number. Also, twenty intermediate kalpas are said to be one incalculable kalpa, and four incalculable kalpas are one great kalpa. In light of that, those four incalculable kalpas represent the kalpas of the creation, presence, destruction, and absence of a world. Buddhas are often described as appearing in a second “incalculable” kalpa.

The designation of a measure of time on the scale of eons, literally meaning “incalculable.” The number of years in such an eon differs in various sūtras that give a number. Also, twenty intermediate eons are said to be one incalculable eon, and four incalculable eons are one great eon. In that case those four incalculable eons represent the eons of the creation, presence, destruction, and absence of a world. Buddhas are often described as appearing in a second incalculable eon.

This eon is literally called “incalculable” but nevertheless has a calculated span of time and therefore, to avoid confusion, its Sanskrit name is used here. The number of years in an asaṃkhyeya eon differs in various sūtras. Twenty “intermediate eons” are said to be one asaṃkhyeya eon, and four asaṃkhyeya eons are one great eon (mahākalpa). In that case those four asaṃkhyeya eons represent the eons of the creation, presence, destruction, and absence of a world. Therefore buddhas are often described as appearing in a second asaṃkhyeya eon.

Literally an “incalculable eon,” though precise numbers are given for its duration. The Abhidharmakośa states that its name does not mean that it is in fact incalculable. The number of years in this eon differs in various sūtras. For example, it is said to be 10 to the power of 49, or 10 to the power of 63 years. Also, twenty intermediate eons (antarakalpa) are said to be one asaṃkhyeya eon, and four asaṃkhyeya eons are said to form one great eon (mahākalpa). In that case those four asaṃkhyeya eons represent the eons of the creation, presence, destruction, and absence of a world. However, it is also used, as apparently in this sūtra, to refer to the longest of all eons, including all others.
