#### 8.2.10.29 datetime.plus ¶

Method: `out =` plus `(A, B)` ¶

  Addition (`+` operator). Adds a `duration`, `calendarDuration`, or numeric B to a `datetime` A.

  A must be a `datetime`.

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

  WARNING: Arithmetic with calendarDuration arguments on datetimes in time zones which use Daylight Saving Time may be buggy.

  Returns `datetime` array the same size as A.
