dátummal

Dátummal is the instrumental singular form of the Hungarian noun dátum, meaning "date." In Hungarian grammar, the instrumental case marks the instrument, means, or accompaniment of an action, or something that accompanies the subject. The noun dátum is a loanword from Latin datum and is the standard term for calendar dates and for date-stamping in documents and data.

Usage: Dátummal is used in contexts where a date serves as the instrument or attribute. Examples include phrases such as "dokumentum dátummal ellátott" (a document with a date attached) or "fájl dátummal megjelölt verziója" (the file version labeled with a date). The construction is especially common in archival, legal, or technical prose; it is less common in everyday speech.

Formation: Dátummal is formed by adding the instrumental suffix -val/-vel to the noun dátum. The plural form for dates is dátumok, which is used in other cases.
