6.10.1 Available Types

class date

An idealized naive date, assuming the current Gregorian calendar always was, and always will be, in effect. Attributes: year, month, and day.

class time

An idealized time, independent of any particular day, assuming that every day has exactly 24*60*60 seconds (there is no notion of "leap seconds" here). Attributes: hour, minute, second, microsecond, and tzinfo.

class datetime

A combination of a date and a time. Attributes: year, month, day, hour, minute, second, microsecond, and tzinfo.

class timedelta

A duration expressing the difference between two date, time, or datetime instances to microsecond resolution.

class tzinfo

An abstract base class for time zone information objects. These are used by the datetime and time classes to provide a customizable notion of time adjustment (for example, to account for time zone and/or daylight saving time).

Objects of these types are immutable.

Objects of the date type are always naive.

An object d of type time or datetime may be naive or aware. d is aware if d.tzinfo is not None and d.tzinfo.utcoffset(d) does not return None. If d.tzinfo is None, or if d.tzinfo is not None but d.tzinfo.utcoffset(d) returns None, d is naive.

The distinction between naive and aware doesn't apply to timedelta objects.

Subclass relationships:

object
    timedelta
    tzinfo
    time
    date
        datetime
