A 'kalpa' is a
Sanskrit word meaning an
aeon, or a long period of time in
Hindu (cf.
Hindu Time Cycles ) and
Buddhist cosmology.
Buddhism
In
Buddhism, there are four different lengths of kalpas. A ''regular'' kalpa is approximately 16 million years long, and a ''small'' kalpa is 1000 regular kalpas, or 16 billion years. Further, a ''medium'' kalpa is 320 billion years, the equivalent of 20 small kalpas. A ''great'' kalpa is 4 medium kalpas, or 1.28 trillion years.

Hinduism
In
Hinduism (cf.
Hindu Time Cycles), it is equal to 4.32 billion years, a "day (day only) of
Brahma" or one thousand
mahayugas, measuring the duration of the world (scientists estimate the age of the universe at 13.7 billion years, cf.
Age of the universe). Each kalpa is divided into 14
manvantara (each lasting 306,720,000 years). Two ''kalpa''s constitute a day and night of Brahma. A "month of Brahma" is supposed to contain thirty such days (including nights), or 259.2 billion years. According to the
Mahabharata, 12 months of Brahma constitute his year, and 100 such years the life cycle of the universe. Fifty years of Brahma's are supposed to have elapsed, and we are now in the ''shvetavaraha-kalpa'' of the fifty-first; at the end of a Kalpa the world is annihilated.
Miscellaneous
The Guinness Book of World Records lists the 4.32 billion year Kalpa as "the longest measure of time."
