About the second and the week

The second

The second (s) is the SI base unit of time. It has been defined since 1967 in terms of the cesium-133 atomic transition, specifically as 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium-133 atom.

The week

The week (wk) equals exactly 7 days, or 604,800 seconds. It is universally used as a planning unit across cultures even though it has no astronomical basis — its origin is religious and cultural, traced back to ancient Babylonian, Jewish, and Roman traditions.
