About Olympiads
An Olympiad = exactly 4 Gregorian years = 1,461 days = 126,227,808 s. In ancient Greece it was the standard historical dating system counting from the first Olympic Games at Olympia in 776 BCE; adopted by Hellenistic historians (Polybius, Timaeus). Modern Olympiads are numbered from Athens 1896. The 4-year cycle is mirrored in US presidential elections and EU Parliamentary terms. 1 Ol = 4 yr = 126,227,808 s.
About Gigayears
A gigayear (1 Ga) = 10⁹ yr ≈ 3.156 × 10¹⁶ s - the timescale of stellar evolution and cosmology. Universe age: 13.787 ± 0.020 Ga (Planck CMB). Sun: 4.603 Ga old; red giant in ~5 Ga. A 0.1 M☉ red dwarf lives ~10,000 Ga. Uranium-238 half-life = 4.468 Ga (used in radiometric dating). Proton decay (GUT prediction): ~10³⁴ yr = ~10²⁵ Ga. 1 Ga = 10⁹ yr.
