In the United Kingdom, while it is regarded as acceptable albeit less common to write month-name day, year, this order is never used when written numerically.However, as an exception, the American shorthand "9/11" is widely understood as referring to the 11 September 2001 terrorist attacks.), and whether the month is represented in Arabic or Roman numerals or by name (e.g. The format has shortened over time but the order of the elements has remained constant.In this format the most significant data item is written before lesser data items i.e. It is consistent with the big-endianness of the Indian decimal numbering system, which progresses from the highest to the lowest order magnitude.Examples for the 9th of November 2003: This sequence is used primarily in the Philippines, English Canada and the United States.This date format was commonly used alongside the little-endian form in the United Kingdom until the mid-20th century and can be found in both defunct and modern print media such as the London Gazette and The Times, respectively.In the United States, it is said as Sunday, November 9, although usage of "the" isn't uncommon (e.g.Sunday, November the 9th, and even November the 9th, Sunday, are also possible and readily understood).
Years are usually counted from a particular starting point, usually called the epoch, with era referring to the particular period of time (Note the different use of the terms in geology).
When numbers are used to represent months, a significant amount of confusion can arise from the ambiguity of a date order; especially when the numbers representing the day, month or year are low, it can be impossible to tell which order is being used.
This can be clarified by using four digits to represent years, and naming the month; for example, "Feb" instead of "02".
The number of days between two dates may be calculated.
For example, "24 January 2018" is ten days after "14 January 2018" in the Gregorian calendar.
