Numerous functions are available in the datetime module for extracting dates and times from strings and formatting them as strings. These functions are available in addition to the standard classes and functions. ![]() The datetime module also offers useful functions, such as datetime.now() and datetime.today(), which return the current date and time, as well as datetime.utcnow(), which delivers the current UTC date and time. The datetime class uses tzinfo objects to represent time in a time zone-aware manner. It enables mathematical operations using dates and times, such as the addition or subtraction of a certain amount of days, seconds, or microseconds. The duration or difference between two dates or times is represented via timedelta objects. The data from both date and time objects are combined in datetime objects. The day and time are stored in time objects (hours, minutes, seconds, and microseconds). The date is stored using date objects (year, month, and day). The module defines the following primary classes: date, time, datetime, timedelta, and tzinfo. The datetime module is a standard Python library, which offers classes for dealing with dates and times. Let us know about these modules in detail. The two modules that are used to perform these conversions are the DateTime module and the Time module. Once they are converted into strings, normal string operations can be performed on them. ![]() A method of storing and performing operations on dates and times is by converting dates and times into strings. ![]() Therefore our codes should also be able to hand dates and times effectively. JavaScript does not support leap seconds.The motivation behind developing any kind of program is to make the common man's life simpler. Some browsers use the current DST (Daylight Saving Time) rules for all dates in history. Please note: All tools on this page are based on the date & time settings of your computer and use JavaScript to convert times.
