What is a second?
A second is the SI base unit of time, defined by the radiation period of the caesium-133 atom (9,192,631,770 cycles). Historically defined as 1/86,400 of a mean solar day, the second was redefined in 1967 using atomic clocks, making it one of the most precisely realized units in all of science.
Common uses of seconds include: Scientific timing and physics experiments; Sports timing and lap records; Computing timeouts and latency measurements; Everyday stopwatch and countdown timing.
What is a week?
A week is a unit of time equal to 7 days or 604,800 seconds. The seven-day week has ancient roots in Babylonian astronomy and Jewish tradition, and unlike other calendar units it has no basis in astronomical cycles, running continuously for millennia.
Common uses of weeks include: Work and school scheduling; Pay periods and billing cycles; Pregnancy and gestation tracking; Project sprints and planning.
