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 Centuries
A century = exactly 100 Gregorian years ≈ 3.156 × 10⁹ s. Standard unit of historical periodisation (the 20th century, the 18th-century Enlightenment). IPCC projects warming and sea-level rise on century timescales. Precession of the equinoxes advances ~1.39°/century, so zodiac constellations no longer match their named seasons. Ice-core and radiocarbon records are commonly displayed at century resolution. 1 century = 100 yr.
