The expanded form of the date (e.g., 31. Dezember 1991) continues to use the little-endian order and the ordinal-number dot for the day of the month. Week numbers according to ISO 8601 and the convention of starting the week on Monday were introduced in the mid 1970s .
ISO prescribes Monday as the first day of the week with ISO-8601 for software date formats. The Slavic , Baltic and Uralic languages (except Finnish and partially Estonian and Võro) adopted numbering but took Monday rather than Sunday as the "first day". [ 25 ]
