Usage notes

• While formally the same lemma, most speakers will use the two senses as singular-only and plural-only respectively, using alternative phrasings like Datenpunkt for a singular datum and Tage to refer to multiple dates.
• In a software context, where data, dates, and data consisting of dates are all common, nonstandard plural constructions like Datümer may be encountered that specifically refer to sense 1.
