To help compare orders of magnitude of different times this page lists times between 1017 seconds and 1018 seconds (3200 million years and 32 000 million years) See also times of other orders of magnitude.
- Shorter times
- 3,500 million years — age of oldest life (bacteria)
- 3,700 to 3,900 million years — age of the Mare Imbrium, the Lower Imbrian epoch
- 4,320 million years — Kalpa, one day of Hindu god Brahma.
- 4,468 million years — half-life of uranium-238
- 4,500 million years — age of the Earth (see: Precambrian)
- 10,000 million years — expected main sequence lifetime of a G2 dwarf star (like the Sun)
- 13,700 ± 200 million years (4e17 seconds) — estimated age of the universe according to the Big Bang theory
- Longer times
