Weeks can be abbreviated as wk, for example 1 week can be written as 1 wk.

The second has historically been defined as 1/60 of a minute or 1/86,400 of a day. The SI defines the second as the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.

The second is the SI base unit for time in the metric system. Seconds can be abbreviated as sec, for example 1 second can be written as 1 sec.
