What Day Is It Today? (Welcher Tag ist heute?) in German

My most embarrassing German mistake didn’t involve grammar.
It involved Tuesday.

I was supposed to meet a friend “am Mittwoch /am ˈmɪtvoχ/,” and my brain decided that meant Tuesday. So on Wednesday I got a message:

« Yak, wo bist du? Heute ist Mittwoch. »
“Yak, where are you? Today is Wednesday.”

I stared at my calendar, my phone, my life, and realized:
I could explain the past perfect tense, but I couldn’t reliably handle days of the week.

Let’s fix that. You’re going to learn how to ask and answer:

• Welcher Tag ist heute? /ˈvɛlçɐ taːk ɪst ˈhɔʏ̯tə/ – What day is it today?
  Plus everything around days, yesterday, tomorrow, and “next week” that real people actually say.
  

Quick Primer: How To Ask “What Day Is It?”

The main phrase you need is:

• Welcher Tag ist heute? /ˈvɛlçɐ taːk ɪst ˈhɔʏ̯tə/
  What day is it today?
  

Two very useful variations:

• Welcher Wochentag ist heute? /ˈvɛlçɐ ˈvɔxn̩taːk ɪst ˈhɔʏ̯tə/
  Which weekday is it today?
  
• Welcher Tag ist heute nochmal? /ˈvɛlçɐ taːk ɪst ˈhɔʏ̯tə ˈnɔxˌmal/
  What day is it again?
  

And a more casual option:

• Was haben wir heute? /vas ˈhaːbn̩ viːɐ̯ ˈhɔʏ̯tə/
  Literally: “What do we have today?” (used like “What day is it?”)
  

Answers are simple:

Heute ist Montag. /ˈhɔʏ̯tə ɪst ˈmoːntaːk/
Today is Monday.

That’s the pattern. Let’s get all the pieces.

The Days Of The Week In German

Here’s your core vocabulary set.

When answering Welcher Tag ist heute?, just plug in:

• Heute ist Montag. – Today is Monday.
  
• Heute ist Freitag. – Today is Friday.
  

You can also include the word “heute” at the beginning or end:

• Montag ist heute. (less common, a bit marked)
  
• Heute ist Montag. (most natural)
  

Stick with Heute ist + Tag for now. Clean and easy.

Talking About Yesterday, Today, and Tomorrow

Real conversations don’t just ask about today. They dance around yesterday and tomorrow too.

Core time words:

Useful sentence patterns:

• Welcher Tag war gestern? /ˈvɛlçɐ taːk vaːɐ̯ ˈɡɛstɐn/
  What day was it yesterday?
  
• Gestern war Dienstag. /ˈɡɛstɐn vaːɐ̯ ˈdiːnsˌtaːk/
  Yesterday was Tuesday.
  
• Welcher Tag ist morgen? /ˈvɛlçɐ taːk ɪst ˈmɔʁɡn̩/
  What day is it tomorrow?
  
• Morgen ist Sonntag. /ˈmɔʁɡn̩ ɪst ˈzɔntaːk/
  Tomorrow is Sunday.
  

These tiny patterns are conversational gold. You’ll use them constantly.

Using “Am” With Days (On Monday, On Friday…)

Germans don’t say “on Monday” with “on”. They use am /am/.

Pattern:

• am + Tag – on [day]
  

Examples:

Useful conversational lines:

• Am Freitag habe ich Zeit. /am ˈfʁaɪ̯taːk ˈhaːbə ɪç tsaɪ̯t/
  I have time on Friday.
  
• Treffen wir uns am Samstag? /ˈtʁɛfn̩ viːɐ̯ ʊns am ˈzamstaːk/
  Are we meeting on Saturday?
  
• Ich arbeite auch am Wochenende. /ɪç ˈaʁbaɪ̯tə aʊ̯x am ˈvɔxn̩ˌɛndə/
  I also work on the weekend.
  

Saying “Every Monday” vs “This Monday” vs “Next Monday”

This is where even intermediate learners get confused.

This / Next / Last

Examples:

• Wir sehen uns nächsten Montag. /viːɐ̯ ˈzeːən ʊns ˈnɛːçstən ˈmoːntaːk/
  See you next Monday.
  
• Letzten Montag war ich krank. /ˈlɛtstən ˈmoːntaːk vaːɐ̯ ɪç kʁaŋk/
  I was sick last Monday.
  

Every Monday (Regular Habit)

To say you do something every Monday, you drop the article and use the day in lowercase:

• montags /ˈmoːntaːks/ – on Mondays / every Monday
  
• dienstags /ˈdiːnsˌtaːks/ – on Tuesdays / every Tuesday
  

Examples:

• Ich mache montags Sport. /ɪç ˈmaxə ˈmoːntaːks ʃpɔʁt/
  I work out on Mondays.
  
• Wir haben dienstags Deutschkurs. /viːɐ̯ ˈhaːbn̩ ˈdiːnsˌtaːks ˈdɔʏ̯tʃkʊʁs/
  We have German class on Tuesdays.
  

Very useful if you want to sound like you live in Germany and not just visit it.

Common Conversation Patterns With Days

Here’s a small “day of the week” toolkit you’ll hear everywhere.

Asking About Plans

Possible answers:

• Ja, Mittwoch passt. /jaː ˈmɪtvoχ past/ – Yes, Wednesday works.
  
• Freitag ist besser. /ˈfʁaɪ̯taːk ɪst ˈbɛsɐ/ – Friday is better.
  
• Am Samstag habe ich schon was vor. /am ˈzamstaːk ˈhaːbə ɪç ʃoːn vas foːɐ̯/ – I already have plans on Saturday.
  

Talking About Today’s Day

Core structure:

• Welcher Tag ist heute? – Heute ist …
  

Examples:

• Welcher Tag ist heute?
  What day is it today?
  
• Heute ist Donnerstag.
  Today is Thursday.
  

Extend a bit:

• Welcher Tag ist heute? Ich habe den Überblick verloren.
  /ˈvɛlçɐ taːk ɪst ˈhɔʏ̯tə ɪç ˈhaːbə deːn ˈyːbɐˌblɪk fɛɐ̯ˈloːʁən/
  What day is it today? I’ve lost track.
  
• Heute ist schon Freitag? Echt?
  /ˈhɔʏ̯tə ɪst ʃoːn ˈfʁaɪ̯taːk ɛçt/
  It’s already Friday today? Really?

Keeping Your Days Straight Like A Calendar-Savvy Yak

Once you can comfortably ask and answer Welcher Tag ist heute?, the whole week stops feeling like a blurry mess of “some weekday probably”.

You can schedule things, complain about Monday, celebrate Friday, and casually say Montags habe ich Sport like someone who has real routines and not just chaos.

And next time someone asks you what day it is, you won’t stare at the ceiling and guess.
You’ll answer cleanly, confidently, and very German:

Heute ist Mittwoch.
