8.2.9.4 datetime.NaT

Static Method: out = datetime.NaT ()
Static Method: out = datetime.NaT (sz)

“Not-a-Time”: Creates NaT-valued arrays.

Constructs a new datetime array of all NaT values of the given size. If no input sz is given, the result is a scalar NaT.

NaT is the datetime equivalent of NaN. It represents a missing or invalid value. NaT values never compare equal to, greater than, or less than any value, including other NaTs. Doing arithmetic with a NaT and any other value results in a NaT.
