What is SI notation in dates?
Date. where YYYY is the year in the usual Gregorian calendar, MM is the month of the year between 01 (January) and 12 (December), and DD is the day of the month between 01 and 31. Other commonly used notations are e.g. 2/4/95, 4/2/95, 95/2/4, 4.2.1995, 04-FEB-1995, 4-February-1995, and many more.
The T doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time. The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).
- HH:MM:SS. Time is based on a 24 hour system. This is frequently referred to as "military time". The 24 hour system is the default format. Example: 14:18:23.
- Prior to 1972, this time was called Greenwich Mean Time (GMT) but is now referred to as Coordinated Universal Time or Universal Time Coordinated (UTC). It is a coordinated time scale, maintained by the Bureau International des Poids et Mesures (BIPM). It is also known as "Z time" or "Zulu Time".
- In India, the DD-MM-YY is the predominant short form of the numeric date usage. Almost all government documents need to be filled up in the DD-MM-YYYY format. An example of DD-MM-YYYY usage is the passport application on.
- Some people may not understand "dd/mm/yyyy". To be clear, use plain English (day/month/year) and include an unambiguous example like 30/4/2010. Here's an example. ________ Date |________| day/month/year - for example 30/5/2010.
- Select a blank cell for locating the age, then enter formula =DATEDIF(A2,B2,"y") into the Formula Bar, then press the Enter key. Note: In the formula, A2 contains the person's date of birth, B2 is the specific date or future date. You can change them as you need.
Formula Description Result =TODAY() Returns the current date. 12/1/2011 =TODAY()+5 Returns the current date plus 5 days. For example, if the current date is 1/1/2012, this formula returns 1/6/2012. 12/6/2011
The ISO date format. The international format defined by ISO (ISO 8601) tries to address all these problems by defining a numerical date system as follows: YYYY - MM - DD where. YYYY is the year [all the digits, i.e. 2012] MM is the month [01 (January) to 12 (December)] DD is the day [01 to 31]
- ISO 8601 Data elements and interchange formats – Information interchange – Representation of dates and times is an international standard covering the exchange of date- and time-related data. It was issued by the International Organization for Standardization (ISO) and was first published in 1988.
- In the United States, the date format begins with the month and ends with the year (MM/DD/YYYY), and this arrangement is relatively unique. In most of the rest of the world, the day is written first and the year last (DD/MM/YYYY), although in some places like China, Korea and Iran, this order is flipped (YYYY/MM/DD).
- Yes. 'Z' stands for Zulu time, which is also GMT and UTC. From http://en.wikipedia.org/wiki/Coordinated_Universal_Time: The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950.
