Английская Википедия:Date and time notation in Finland
Шаблон:Use dmy dates In Finland, the usual way of writing dates in normal text is with the months spelled out.[1][2] The format varies according to the language used. In Finnish, a full stop (full point, dot or period) is placed after the day to indicate an ordinal: Шаблон:Lang; furthermore, the month is in the partitive case, always marked by Шаблон:Lang. The month can also be written first, now in genitive case (the day and the abbreviated word Шаблон:Lang, 'day', are in essive case as above): Шаблон:Lang.Шаблон:Citation needed In Swedish, the full stop is not used and the month is in nominative (without inflection): Шаблон:Lang.
The date can be preceded by the weekday (also lower case), in Finnish in essive case: Шаблон:Lang, Шаблон:Lang. The Finnish language has month names differing from most other languages; three letter abbreviations are not used in Finnish, and the months are not capitalised in either language (they are not considered proper names). In spoken Finnish in a context where it is clear people may say the short form of the month e.g. Шаблон:Lang for Шаблон:Lang 'October', but never in formal writing as several months also can be times of the year e.g. Шаблон:Lang 'December' whereas Шаблон:Lang is yule or Christmastide; Шаблон:Lang 'June' is similar to Шаблон:Lang 'summer'.
In the Sami languages (Inari Sámi, Northern Sámi and Skolt Sámi) the date can be given with the month first, but then spelt out in essive case: Шаблон:Lang, Шаблон:Lang, Шаблон:Lang.Шаблон:Citation needed
The all-numeric form for dates is in the order day–month–year, using a full stop as the separator – for example: 31.5.2002 or 31.5.02. Years can be written with two or four digits, after the turn of the millennium usually with four, and numbers may be written with or without leading zero. The numeric form is often used in lists, letterheads, etc. A form with a stroke is also common in Swedish, especially in handwritten text: 31/5 2002 or 31/5 -02. The weekday may be prepended: Шаблон:Lang.
The ISO 8601 notation (2002-05-31) is not used in normal text in Finland, but it is understood and used in some other contexts (mostly machine-generated).
Numbering of weeks is used in Finland, and is simply expressed as in Шаблон:Lang; Шаблон:Lang ('(week) 28') in both writing (abbreviated Шаблон:Lang in Finnish[3] and Шаблон:Lang in Swedish[4]) and speech, as well as on labels and in computer notation. The week begins with a Monday and week 1 is the week containing the year's first Thursday.
Time in Finland often uses the 12-hour clock in the spoken language and idiomatic expressions. 24-hour notation is used in writing, with a full point as the standardised and recommended separator (e.g. 15.07 or 8.27). However, a colon is almost exclusively used instead of a full pointШаблон:Citation needed in computing environments, especially in Sámi languages. The conventions are the same for Finnish and Swedish.
