Classes of datetime module :

The list of standard libraries we can use to work with date and time.

datetime: The datetime is a built-in module that provides functions to handle many complex functionalities involving the date and time. It has a date, time, timezone, and timedelta classes to work with date and time.
calendar: In Python, a calendar is a built-in module to work with calendar-related activities and operations. In the calendar module, by default, Monday is the first day of the week, and Sunday is the last day of the week as per the Gregorian calendar (the calendar introduced in 1582 by Pope Gregory XIlI).
time: time module provides a different function to work with time-related activities where dates are not needed.

Let’s see some more details about classes in datetime :

date Class in DateTime

We can represent the date object using the date class and the date class initializes the native date. It always considers the Gregorian calendar ( format YYYY-MM-DD). The constructor of the date class takes three parameters which include year, month, and day.

Syntax:

datetime.date(year, month, day)

time Class:

To work with time, we can use the time class from the datetime module. It is independent of day.

Syntax:

datetime.time(hour, minute, second, microsecond, tzinfo, *, fold)

datetime Class

The datetime class contains information about both date and time. It Assumes the Gregorian Calendar and there are 86400 seconds every day.

Syntax:

datetime.datetime(year, month, day, hour, minute=0, second, microsecond, tzinfo=None)

TimeDelta:

A timedelta represents a duration which is the difference between two dates, time, or datetime instances, to the microsecond resolution.

Using the datetime module's timedelta class we can add or subtract weeks, days, hours, minutes, seconds, microseconds, and milliseconds from a given date and time.

Syntax:

class datetime.timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0)

Returns: Date
