14 manvantaras
The thin teal marks are the sandhyās — twilight junctions between Manus, each as long as a Satya-yuga. Hover a wedge for its ruler; click to descend.
Kalpa (Day of Brahma)
कल्पOne day of Brahma — 1,000 chatur-yugas, or 14 manvantaras with their junctions: 4.32 billion human years. At its close the naimittika pralaya falls, and Brahma's night, of equal length, follows. The present kalpa is the Shveta-Varaha.
The bright half of Brahmā’s day-and-night — a day of creation through which fourteen Manus rise and pass. The present day is the Śveta-Vārāha kalpa.
If this whole 4.32-billion-year day were compressed to a single 24-hour day, all of recorded human history (~5,000 years) would flash by in about a tenth of a second.
