The weekday function in Python’s calendar module returns the day of the week for a given date. This function is useful for determining the day of the week for any given date.

The leapdays function in Python’s calendar module returns the number of leap years within a specified range of years. This function is useful for calculating the number of extra days added due to leap years within a given period.

The isleap function in Python’s calendar module checks if a given year is a leap year. This function is useful for determining whether a year has an extra day in February, which occurs every four years with some exceptions.

The month function in Python’s calendar module returns a multi-line string representing a month’s calendar. This function is useful for generating a text-based calendar for a specified month and year.

The calendar function in Python’s calendar module returns a multi-line string representing a year’s calendar. This function is useful for generating a text-based calendar for a specified year.

The datetime.astimezone function in Python’s datetime module converts a datetime object from one time zone to another. This function is useful for converting times between different time zones, such as when scheduling events across multiple regions.

The datetime.replace function in Python’s datetime module creates a new datetime object with some fields replaced by new values. This function allows you to modify parts of a datetime object, such as the year, month, day, hour, minute, second, and microsecond, without changing the original datetime object.

The datetime.combine function in Python’s datetime module combines a date object and a time object into a single datetime object. This is useful when you need to create a datetime object from separate date and time components.

The timedelta function in Python’s datetime module represents a duration, i.e., the difference between two dates or times. This function is useful for performing arithmetic operations on dates and times.

The date.fromtimestamp function in Python’s datetime module converts a time expressed in seconds since the Epoch to a date object representing the local date. This function is useful for converting Unix timestamps to human-readable dates.

The date.today function in Python’s datetime module returns the current local date. This function is useful for capturing the present date in your programs.

The datetime.strptime function in Python’s datetime module parses a string representing a date and/or time according to a specified format and returns a datetime object. This function is useful for converting formatted date and time strings into datetime objects.

The datetime.fromtimestamp function in Python’s datetime module converts a time expressed in seconds since the Epoch to a datetime object representing local time. This function is useful for converting Unix timestamps to readable date and time formats.

The datetime.utcnow function in Python’s datetime module returns the current UTC (Coordinated Universal Time) date and time. This function is useful for capturing the current time in a timezone-independent manner.

The datetime.today function in Python’s datetime module returns the current local date and time. This function is useful for capturing the present moment in your programs, including both date and time information, similar to the datetime.now function.

The datetime.now function in Python’s datetime module returns the current local date and time. This function is useful for capturing the present moment in your programs, including both date and time information.

The time_ns function in Python’s time module returns the current time in nanoseconds since the Epoch. This function is useful when you need higher precision for time measurements compared to the time function, which provides time in seconds.

The process_time function in Python’s time module returns the CPU time (in fractional seconds) used by the process. This function is useful for measuring the CPU time consumed by your program, independent of wall clock time.

The monotonic function in Python’s time module returns the value (in fractional seconds) of a monotonic clock, i.e., a clock that cannot go backwards. This function is useful for measuring elapsed time without being affected by system clock updates.

The perf_counter function in Python’s time module returns a high-resolution timer value as a floating-point number. This function is useful for measuring short durations with high accuracy, such as performance testing or benchmarking code.

The strptime function in Python’s time module parses a string representing a time according to a format and returns a struct_time object. This function is useful for converting formatted time strings into structured time data.

The strftime function in Python’s time module formats a struct_time object or a tuple representing a time as a string according to a specified format. This function is useful for creating human-readable representations of time and date.

The mktime function in Python’s time module converts a struct_time object representing local time to a time expressed in seconds since the Epoch. This function is useful for converting structured time data back into a timestamp.

The localtime function in Python’s time module converts a time expressed in seconds since the Epoch to a struct_time representing local time. This function is useful for converting timestamps into a more structured and easily readable local time format.

The gmtime function in Python’s time module converts a time expressed in seconds since the Epoch to a struct_time in UTC. This function is useful for converting timestamps into a more structured and easily readable format.
