Method Reference: datetime.isdst

datetime: TF = isdst (T)

Determine which datetime values fall in daylight saving time.

TF = isdst (T) returns a logical array TF of the same size as the input datetime array T, where each element is true if the corresponding datetime falls within daylight saving time in its time zone, and false otherwise. If T has no time zone, or for Not-A-Time (NaT) values, the corresponding element of TF is false.
