✕Common Mistakes
Was ist morgen für ein Tag?
The preposition "für" always takes the accusative; make sure the article matches the noun's gender and case.
Was ist Morgen für ein Tag?
"Morgen" as a noun (the morning) is capitalized; here it is an adverb meaning 'tomorrow' and stays lowercase.
Was ist morgen für einen Tag?
The noun "Tag" is masculine; the correct indefinite article in accusative is "einen" only when the noun is definite. With "ein" it stays unchanged because the article is indefinite and the noun is singular.

Cultural Tip
In German, asking about the day of the week is common in both formal and informal contexts. Note that "Tag" refers to the calendar day, not the quality of the day (e.g., "ein schöner Tag"). When you need to be more polite or formal, you can preface the question with "Entschuldigung" or "Könnten Sie mir sagen…". Also, regional dialects may replace "für ein" with "für'n" in colloquial speech, but the standard form is preferred in learning materials.
