==Date==

In [[Republic of Ireland|Ireland]], the date is written in the order "day month year".<ref name=genea>{{cite web|url=http://www.mc-research.com/home/dates/dates.htm|title=Genealogical and Historical Research Service in Ireland|website=www.mc-research.com}}</ref> The separator varies (cf,<ref name=genea/><ref name=plain/>)

''31 December 1992'' is also used, or in [[Irish language|Irish]], ''{{lang|ga|31 Nollaig 1992}}''. When dates are spoken, they are generally given in "day month year" order: "the 31st of December 1992", or sometimes in "month day year": "December the 31st 1992". [[Ordinal indicator]]s may also be used (''31st December 1992''; ''22nd April 1953'', etc.). In Irish, these are ''1<sup>d</sup>'' (short for ''chéad''), ''2<sup>a</sup>'' (short for ''dara''), with all subsequent digits followed by ''-ú''.

Weeks are generally referred to by the date on which they start, with [[Monday]] often treated as the first day of the week, for example "the week commencing 10 August", although some calendars give [[Sunday]] as the first day of the week.

==Time==

The 12-hour clock is the dominant format in Ireland, although the 24-hour clock is gaining in use.<ref name=plain>{{cite web|url=http://www.plainenglish.ie/build-your-own-style-guide-dates-and-times/ |title=Decide how to write dates and times with our style guide |author=Sarah Marriott |work=Plain English Ireland}}</ref> In the [[Irish language]], the 12-hour clock is used. The abbreviation ''a.m.'' is used, but it stands for ''ar maidin'' ("in the morning") rather than ''[[ante meridiem]]''. Times after 12:00 are described as (for example) 3:00 ''i.n''., short for ''iarnóin'' (afternoon).<ref>{{cite book|url=https://books.google.com/books?id=G8pzCgAAQBAJ&q=iarn%C3%B3in+i.n.&pg=PT117|title=Colloquial Irish: The Complete Course for Beginners|first1=Thomas|last1=Ihde|first2=Maire Ni|last2=Neachtain|first3=Roslyn|last3=Blyn-LaDrew|first4=John|last4=Gillen|date=27 August 2015|publisher=Routledge|isbn=9781317305286|via=Google Books}}</ref>
