00:00Hello, welcome to the Transcendent. In this video, we'll learn HTML dates and times.
00:19And how does this function works? Dates and times, let's get into it.
00:24Anyone who is programmed in any language knows that working with time-related data can quickly become chaotic.
00:31Fortunately, HTML simplifies this process.
00:35HTML provides a dedicated element for marking anything related to timestamps, including individual moments, full dates, or defined durations, the time element.
00:45We use the time element to structure time-related data so that both browsers and other systems can interpret it accurately.
00:51Time is tricky, but HTML keeps it neat.
00:55The time element ensures computers don't misinterpret your carefully planned schedules.
01:00The time element consists of an opening and closing tag, defining a specific moment in time.
01:06For example, an opening time tag followed by May 8th, then the closing time tag.
01:12Alternatively, dates can be formatted with a year, May 8th, 2025.
01:17Some prefer writing dates differently, like 8th, May 2025.
01:22We can use any human-readable format between the tags.
01:26This is the content displayed on the webpage, what people genuinely perceive and experience.
01:32Dates may look different, but the time element ensures websites display them properly.
01:37The whole purpose of the time element is to make sure computers can interpret the exact moment or duration it represents.
01:44To achieve this, we use something called an HTML attribute.
01:49We haven't explored HTML attributes yet, but we can apply them to any HTML element, which we'll cover in detail later.
01:56For now, let's focus on the attribute that allows us to define precise data about a date or a time information computers can accurately process.
02:06The time element helps computers understand dates without confusion.
02:10If only our alarms were as reliable.
02:13In HTML, the element name always comes first, positioned immediately after the opening less than sign.
02:20Next, we add a space, then write the attribute name, followed by an equal sign, and finally place the attribute value inside quotes.
02:28For the time element, we use the date-time attribute, written as date-time, all one word.
02:35For example, date-time equals 2025-05-08.
02:41The date-time attribute follows a specific machine-readable format, ensuring accuracy when processing time-related data.
02:49Since consistency matters, we must adhere to this standardized format.
02:53Computers love precision, if only people followed meeting times as strictly as HTML-date-time.
03:01May 8th can be formatted as May 8th, when including the year.
03:05Regardless of how dates are written for people, the machine-readable version in the date-time attribute follows a strict format, year-month and date.
03:13For example, May 8th, 2025, the year in four digits, the month in two digits, and the day in two digits.
03:20Alternatively, if we only have a month and year, we omit the day.
03:25Or, if we only have a year, we simply use the four-digit year value.
03:30Key takeaway.
03:31Computers prefer precision.
03:33Too bad humans can't agree on one way to write dates.
03:37We don't always need to spell out the full date.
03:40Websites often display timestamps in natural phrases like,
03:432 hours ago, or 20 days ago, making them more user-friendly.
03:48However, the date-time attribute still follows a strict machine-readable format, ensuring accuracy for data processing.
03:56Humans can write dates in multiple ways, but computers require a standardized structure to interpret them correctly.
04:03People have flexibility with dates, but computers demand structure.
04:07We can also define time values using the time element.
04:11The machine-readable format follows a 24-hour clock system.
04:15Seconds and fractional seconds can be included or omitted.
04:20We can also specify a time zone.
04:22For example, 1545 to 0500 represents 1545, 345 p.m.
04:29in a time zone 5 hours behind Greenwich Mean Time, GMT, the same as New York City's time zone.
04:36Of course, we can combine both date and time.
04:39In the date-time attribute, the date is written first, followed by the time.
04:45We can separate them with T or simply use a space.
04:49Key takeaway.
04:50Computers are precise with time, but humans still struggle with daylight savings.
04:55There are multiple ways to format machine-readable daytime, and each variation is valid.
05:01These rules aren't exclusive to HTML.
05:03They apply to many programming languages as well.
05:06There are hundreds of correct combinations for structuring date-time data.
05:11Whenever needed, it's best to check the formatting guidelines to ensure accuracy.
05:16The time element, along with its date-time attribute, enables precise communication of time-related data,
05:23making it universally understandable for computers.
05:26Key takeaway.
05:27Computers are flexible with date-time formats.
