Seconds

The second is the SI base unit of time, defined since 1967 as the duration of exactly 9,192,631,770 cycles of radiation from the caesium-133 atom. Atomic clocks based on this definition lose less than one second in 300 million years. The second underpins all timekeeping in modern civilisation — from GPS satellite synchronisation to internet protocols and financial transaction timestamps.

Decades

The decade is a unit of time equal to exactly ten years, derived from the Greek deka (ten). While not a formal SI unit, it is widely used in demography, economics, history, and popular culture. In science, decade-scale processes are important in climatology (decadal temperature averages), epidemiology (ten-year cohort studies), and astrophysics (stellar variability cycles).
