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 Tropical Years
The tropical year = time from March equinox to the next = 365.24219 days = 31,556,925.2 s - the year that governs the seasons. The Gregorian 97/400 leap rule approximates it as 365.2425 days, leaving a residual drift of only ~26.8 s/year. The tropical year shortens ~0.53 s per century due to tidal deceleration. Persian Solar Hijri and Mayan Haab' calendars also approximate it. 1 a_trop ≈ 365.24219 d.
