#### 8.2.10.25 datetime.minus ¶

Method: `out =` minus `(A, B)` ¶

  Subtraction (`-` operator). Subtracts a `duration`, `calendarDuration` or numeric B from a `datetime` A, or subtracts two `datetime`s from each other.

  If both inputs are `datetime`, then the output is a `duration`. Otherwise, the output is a `datetime`.

  Numeric B inputs are implicitly converted to `duration` using `duration.ofDays`.

  Returns an array the same size as A.
