Pühapäevast

Pühapäevast is the Estonian noun pühapäev (Sunday) in an oblique form that is used to express starting point in time. It denotes “from Sunday” or “as of Sunday” and appears in contexts that specify when something begins or changes. The form is most common in written language and official or public communications, such as schedules, notices, and announcements.

In everyday usage, pühapäevast typically occurs with prepositions or constructions that introduce a starting point. Common phrases include pühapäevast alates, which translates to “starting from Sunday.” The phrase is used to indicate that a rule, price, or timetable becomes effective on Sunday and continues onward. Examples: Pakkumine kehtib pühapäevast. (The offer is valid from Sunday.) Uus ajakava jõustub pühapäevast. (The new timetable takes effect from Sunday.) Pühapäevast alates saavad reisijad kasutada uut liini. (From Sunday, passengers can use the new line.)

Etymology and form: pühapäev is a compound of püha (holy) and päev (day), historically meaning the holy day. The suffix -ast marks a common oblique-case form used in time expressions to indicate starting points or intervals, with the exact case depending on the syntactic construction. The word is primarily a feature of Estonian grammar and is most readily understood within the context of dates and schedules.
