About the second and the day

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 day

The day (d) equals exactly 86,400 seconds, or 24 hours. This is the conventional 'civil' day used in calendars and contracts. The actual solar day (one full rotation of Earth relative to the Sun) varies slightly throughout the year; the difference is reconciled in atomic time scales using leap seconds.
