The legal and cultural expectations for date and time representation vary between countries, and it is important to be aware of the forms of all-numeric calendar dates used in a particular country to know what date is intended. Many countries have adopted it as their sole official date format, though even in these areas writers may adopt abbreviated formats that are no longer recommended.

Unsourced material may be challenged and removed.If date of birth is not known or cannot be obtained, provision should be made to collect or estimate age.
Collected or estimated age would usually be in years for adults, and to the nearest three months or less for children aged less than two years. Additionally, an estimated date flag or a date accuracy indicator should be reported in conjunction with all estimated dates of birth. For data collections concerned with children's services, it is suggested that the estimated date of birth of children aged under 2 years should be reported to the nearest 3 month period, i.
Again, an estimated date flag or date accuracy indicator should be reported in conjunction with all estimated dates of birth. The linking of client records from diverse sources, the sharing of patient data, and data analysis for research and planning all rely heavily on the accuracy and integrity of the collected data.
In order to maintain data integrity and the greatest possible accuracy an indication of the accuracy of the date collected is critical. The collection of an indicator of the accuracy of the date may be essential in confirming or refuting the positive identification of a person. For this reason it is strongly recommended that the data element Date—accuracy indicator, code AAA also be recorded at the time of record creation to flag the accuracy of the data.
Wherever possible and wherever appropriate, date of birth should be used rather than age because the actual date of birth allows a more precise calculation of age. When date of birth is an estimated or default value, national health and community services collections typically use or or as the estimate or default for DDMM. It is suggested that different rules for reporting data may apply when estimating the date of birth of children aged under 2 years because of the rapid growth and development of children within this age group which means that a child's development can vary considerably over the course of a year.
Thus, more specific reporting of estimated age is suggested. Standards Australia Sydney: Standards Australia. For the provision of State and Territory hospital data to Commonwealth agencies, this field must:.

Where the date of birth is estimated, this should be indicated when the data is submitted using the date estimate indicator.
For the provision of State and Territory hospital data to Australian Government agencies this field must:. For components of the Date of birth which are unknown, 00 should be recorded, for example if a child was born in July but the day of birth is unknown record The HPA collection requires a different format from the standard.
The main applicant is the person or principal person whose name appears first on the home purchase assistance application form.Regardless, no one seems to know why Americans first started putting the month first.
Thus, before people were too overly concerned with the likes of spelling, grammar, and conventions such as this, they just wrote it as was most convenient in whatever context. In fact, in at least one case we found, both formats even occurred in the same sentence! Interesting side fact, the Declaration of Independence was not signed in July as is commonly stated, but rather in August of that year.
However, month-first was not exclusively used and the day-first format is also seen in documents from the s. By the last quarter of the 19th century, Mark Twain was writing the date month-first in his correspondence with friends, and by the early part of the 20th century, American newspapers reporting on the sinking of the Titanic had the month-first as well.
Of course, for the most famous speech of his career, President Franklin D. Although we find it normal, our month-first arrangement to the rest of the world makes little sense, being what one commentator has called middle-endian computer speak for bass-ackwards. Endian refers to the organization of binary data storage whereby the most significant byte 8-bit unit of data is typically stored first in the smallest address, on the left or last in the largest address, on the right.
When it comes to bytes of numbers, the first left digit is usually the most significant and will have the greatest value e. In Chapter 4, Gulliver learns that a source of discord among the Lilliputians and the Blefuscuans was a royal decree regarding the proper way to break into a soft-boiled egg :. The emperor. Some of the populace resented this, and a bloody war ensued between the big-endians who wanted to be free to break their eggs as they chose, and the little-endians who followed the emperor.
In staging this silly egg war, Swift satirized holy wars — such as those that raged between Protestants and Catholics during the 16th and 17th centuries — and more particularly their root causes.
At least one commentator has opined that egg breaking may be a nod to the relatively slight variations between Protestant and Catholic communion rites during that period. In any event, clearly Swift was saying that arguing over such trivial matters is absurd, and everyone should be free to choose.
Were this to be proposed for date formats, clearly the rest of the world would quickly vote to eliminate our middle-endian method. But when I went to renew my visa, they told me I was already a month late!
I tried to explain the American convention of writing dates and they were extremely sceptical. I found it surprising that a visa office had never encountered this before. The reasons are simple; this string format sorts correctly. It is not standard yet, but is gaining support.
It really depends on how you look at it. You could say the months represent days in a year or just 12 months in a year. If looking at the point, DD-MM-YYYY is logical, with day ranging from to 31, months representing theand years representing infinite, so small-middle-large. But from the 12 point of view, MM-DD-YYYY is just as logical because months aredays are to 31, and year is infinite, so small-middle-large again.
Our max date format would be compared to The only way the DD-MM-YYYY format would not be middle-endian is if the months were actually written in format, so or leap yearwhich why include the month day if your including the year day? So again, it is all in how you look at it. It is big-endian vs small-endian, with a subgroup of small-endians debating what part of the small end is the small end, because we like being difficult.
Ordering something according to sequence or first come get first place is natural and we everybody accept it. Therefore people seem putting DAY first more comfortable. The converse in fact, it was the popular end date, and still is, but the war carried on for several more weeks.
I assumed it was down to the way the dates were spoken. July 4th being an obvious example. Here we would say 4th of July.
So I come across the American format on a daily basis. Either because server Admins forgot to change their date formats or, as is becoming increasing more likely, couldnt be bothered.When date input was added by HTML5, many believed that it would offer the users a friendly, interactive and known method of entering a date on a website. However; this new addition has failed to live up to the expectations and the major reason behind it remains the fickle nature of the format of the input given by the user.
Originally, the date input attribute was designed as a form element to pick values through a datepicker. The problem however, lies in the implementation of datepicker which changes from browser to browser. Now there is no said rule in HTML5 that would allow the web designers to change the format in which the date element picks values.
Therefore, the rigidness of the date element prompted designers to look for other ways to alter the format of the date to be entered by the user. How are we going to achieve this using the date element given that it does not give the liberty to change the date format? If the date format is absolutely critical to the functioning of the webpage, then we will need to make that choice.
This solution has the disadvantage that there is no popup date picker. The solution would be go back to one of the jquery datepicker widget. About Site Map.Mar 20, AM by rubab a.

How to write date and place of birth. Thread starter xerexes Start date Apr 25, When writing the date and place of birth in a parentheses next to someone's name, do you need commas between the date and location?Change Date Formats in Excel As per your Country Location (Easy)
PaulQ Banned UK. Part of the confusion is self-made. If you write the date, 12 Mayand add brackets to the country or territory, it becomes 12 MayParis France thus requiring only one comma and being absolutely clear.
I personally like Paul's solution, but some of my fellow Americans might object. If you're using US style, as you do in your example, I'd suggest a semicolon after the year in order to separate the time and place May 12, ; Paris, France. I'm using US style and I'm proofreading a short book. The author never uses the semicolon there.
In the first few pages he has used a comma between date and city like my first example, and then just stopped doing it and wrote it like the second example! Which one do you think is the more proper? I'm thinking the one without the comma. Egmont Senior Member Massachusetts, U. A comma breaks a sentence or phrase into components. If you do not use a comma, if you write "May 12, Paris, France," you are breaking it into three components: "May 12," " Paris," and "France.
A separator of some sort is required - not optional - between the year and the country. You can use a comma; you can use a semicolon, as Parla suggested, you can use the word "in," and there are perhaps other choices as well - but leaving it with no separation is confusing to a reader. Unless the author of your short book wants to confuse his readers, do not leave it with no visible separation. Even if readers can eventually figure out what he means, they will waste mental energy in doing that so they will have less mental energy left to understand or enjoy what he wrote.
I think I'll go with the comma since it's already used in the text. I appreciate your help. You must log in or register to reply here.Template:Birth date will return a person's date of birth. Using this template rather than simply inserting the date into articles allows for the inclusion of hidden metadata about the date. This metadata can be used by web browsers and other software tools to extract the details, and display them using some other website or mapping tool, index, or search them.
The df day first and mf month first parameters indicate the intended date format to display. The appropriate parameter should be set to "y" or "yes", e. The default output of this template is to display the month before the day.
This default may not be appropriate for articles about people from parts of the world where the day precedes the month in a date. In such articles the parameter, "df", should be set to display the day before the month. The parameter "mf", while not actually used by the template, will indicate that month first format is intended.
Using these parameters can assist bots or other automated processing to detect which date format is intended; leaving the format as default may lead an editor or bot to change the format to an unintended value.
Do not specify both "df" and "mf" parameters in the same use of the template, as these formats are mutually exclusive. Note: For the "foundation", "built" and similar set-up dates of companies, buildings etc. Because the ISO standard requires the Gregorian calendarthis template should not be used if the date is given in the Julian calendar.
