The fact that it is easy for the human to read date/time in many forms, but when coming to machines, it is difficult to parse, by then <time> comes in. This <time> tag defines a particular period in time and specifying the date and time for the particular web pages so they are very useful too and represent the human-readable tag. This human-readable is a valuable format of internet protocols. The <time> tag is supported in HTML 5 but not in HTML 4.01 version.
The time can be defined in the following ways:

This time element supports global and event attributes; apart from that, a very important attribute is Date Time. To display the values like ‘Monday’, ‘Friday’ date-time attribute is represented.

Examples to Implement HTML time Tag
This tag can also be used without using datetime Attribute to display either date or time. The following are some examples:
Example #1 – using a <time> tag.
<!DOCTYPE html> <html> <head> <title> HTML Time Tag </title> </head> <body style="text-align:left;"> <h2>HTML Time Tag demo</h2> <p> India celebrate as <time>2020-01-26</time> Republic day </p> </body> </html>
Making time element to the title attribute to show detailed information of the user in the format with the nice human-readable format or either machine-readable format.
<!DOCTYPE html> <html> <body> <h2> <center> Date Time Example </center> </h2> <h3>The Stand- Up Comedy show starts at <time datetime="2018-07-04T20:00:00Z">20:00</time> coming Saturday.</h3> <h3>The preview show starts in <time datetime="PT3H0M3S">5h 1m 0s</time>.</h3> </body> </html>
In the below Output, the time tag instructs the browser about the text used between the attribute is a time reference ( 5 h 1m 0s) but doesn’t display the time attribute.
Example #3 – Using Css.
<!doctype html> <html> <body> <article> <body style="background-color:yellow;"> <h1>Title of the document</h1> <p>Introduction to the Article</p> </article> <footer> <p>This content is published on <time>2016-1-20</time>.</p> <p>Our shop opens at <time>08:00</time>.</p> </footer> </body> </html>
Example #4 – Using pubdate attribute.
<!DOCTYPE html> <html> <body> <article> <h1>A good Article</h1> <p>Introduction on a given Article.</p> <footer> <p>Content published on <time datetime="2019-02-04" pubdate>February the 4th, 2019</time> </footer> </article> </body> </html>
Therefore, we had learned how to work with the <time> tag and also, we came to know how the web crawlers interpret the date and time on the web page.
