Different date conventions is something that professional translators must pay attention to. Whether a date is for the US, Europe or Asia, it is essential to use the correct date convention for the intended translation audience. But this is a cultural adaptation, and the translator must be familiar with and know how dates are written in the target language, as well as of course know the correct way of writing them in his or her source language.

The most widely used date convention in the world is the one that follows this order

DAY – MONTH – YEAR date convention

It is used in

  • the whole of Europe
  • Central America (with the exception of Belize, which follows month-day-year)
  • South America ,
  • Mexico, the whole of Africa,
  • Oceania,
  • in the majority of Asian countries.

MONTH – DAY – YEAR date convention

It could be argued that the M-D-Y (month, day, year) is a more logical way of organizing files in a computer and many computer people use it to that end all over the world. It is the preferred date convention in

  • United States,
  • Belize
  • Micronesia.

It is also an alternative to the most widely used D-M-Y format in the following countries

  • Philippines,
  • Saudi Arabia
  • Canada.

YEAR – MONTH – DAY date convention

This is the only ISO-approved date convention (ISO 8601). As such, its use is considered more international and neutral. The ISO standard says that date and time values have to be ordered logically from the largest to smallest unit of time. Thus we begin with the year, then the month (or week), followed by the day, hour, minute, second, and fraction of second. The order of the date convention corresponds to a logical descending chronological order, with the exception of date representations for negative years. ISO8601 date format allows dates to be sorted naturally by, for example, computer systems.

This date convention format is used in the following countries

  • Japan,
  • China,
  • North Korea,
  • South Korea,
  • Taiwan,
  • Hungary,
  • Lithuania
  • Iran,

and is also used secondarily in some countries in Europe and Asia.

If you are ordering Spanish translations, we recommend to use the popular day – month – year and not to use zeros when either the day or the month is a single digit. For example, 4/5/2016 is preferable to 04/05/2016. In cases where readers may find it confusing to discern which is the month and which is the day, the best alternative is to spell out the name of the month in full or in abridged form (12-JAN-2017 or January 12, 2017).

different calendar date conventions

You have pobably noticed something by now: the translation of a date has more to do with the country in which your translation will be read than with the target language.  For example, if you are in need of English translations because you have been landed documents in another language, the date convention will depend on whether you are following British English or American English – or perhaps you are seeking a “neutral” ISO date convention. However, if you are addressing Spanish markets (follow the link to read more on “A guide to breaking your business in the Spanish-speaking market”) or Spanish speakers in the US and you have dates in your documents or websites that need to be translated from English to Spanish, we would strongly recommend to maintain the popular M-D-Y format.
