a_trop = t_P × 1.708419614e-51
About Planck Time
The Planck time (t_P) = √(ℏG/c⁵) ≈ 5.391 × 10⁻⁴⁴ s — the time for light to travel one Planck length (~1.616 × 10⁻³⁵ m). Below this scale, general relativity and quantum mechanics both break down; a theory of quantum gravity is needed. No physical process or instrument approaches this timescale — it is a theoretical lower bound. Introduced by Max Planck in 1899. 1 t_P ≈ 5.391 × 10⁻⁴⁴ 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.
