What method can one use to alternate a variable which is dependable by time?

For example, this week var = Office, then next week var = Oncall?

The resulting script will be using crontab to output the contents of var depending on which week it was.

Thanks.

You can use date +%W to check what week number of the year it is (starting Monday).

You can alternate between the two with e.g.

if (( $(date +%W) % 2 ))
then
  var=Office
else
  var=Oncall
fi
