Dátumon

Dátumon is the locative singular form of the Hungarian noun dátum, meaning “the date.” It is used to denote a location in time, effectively translating to “on the date.” The form is created by adding the locative suffix -on to the stem dátum (dátum → dátumon), in line with Hungarian vowel harmony. The plural form is dátumokon, and related case forms include dátumról (from the date) and dátumra (to the date).

Dátum is a loanword that entered Hungarian through German Datum, with its ultimate origin in Latin data. The word today denotes a calendar date or a point in time used as a reference. The locative form dátumon appears most often in formal, administrative, or legal language, where the date is treated as a reference point or temporal location. In everyday speech, speakers more commonly use explicit dates or calendar expressions rather than relying on the locative form.

In usage, dátumon can combine with other modifiers to specify a particular date, for example in phrases that designate actions or statuses tied to a specific date. While not as common in casual conversation, the form remains part of the standard noun-case system and can be found in official documents, forms, and written Hungarian.
