Distributive-temporal case

This case in Hungarian language can express how often something happens (eg. monthly, daily); it can vary with the Distributive case at words of temporal meaning.

This case in Finnish language can express that something happens at a frequent point in time (e.g. "on Sundays" is sunnuntaisin), or an origin (e.g. "born in" is syntyisin). It is restricted to a small number of adverb stems and nouns. The ending is -sin. For example, the root päivä (day) has the plural päivi-, and thus the temporal distributive päivisin ("daily" or "during the days").

The temporal distributive case specifies when something is done, in contrast to the the distributive case, which is specifies how often something is done, as in regular maintenance. These sentences are a good example: Siivoan päivisin vs. Siivoan päivittäin. The former means "I do the cleaning during the days", whereas the latter means "Each day, I clean".

If the plural has another form, either joka (each) or the essive case is used. For example, uusivuosi (New Year) is either joka uusivuosi or uusinavuosina, respectively.
