pandas.DatetimeIndex.strftime#

DatetimeIndex.strftime(date_format)[source]#

Convert to Index using specified date_format.

Return an Index of formatted strings specified by date_format, which supports the same string format as the python standard library. Details of the string format can be found in python string format doc.

Formats supported by the C strftime API but not by the python string format doc (such as “%R”, “%r”) are not officially supported and should be preferably replaced with their supported equivalents (such as “%H:%M”, “%I:%M:%S %p”).

Note that PeriodIndex support additional directives, detailed in Period.strftime.

Parameters:

date_formatstr: Date format string (e.g. “%Y-%m-%d”).

Returns:

ndarray[object]: NumPy ndarray of formatted strings.
