Questions & Answers about I dag jobbar jag hemifrån.
Both i dag and idag are used in modern Swedish.
- i dag (two words) is the more traditional/standard spelling and is what you’ll often see in textbooks and more formal writing.
- idag (one word) is also very common, especially in everyday writing, online, and in messages.
They mean exactly the same thing: today.
As a learner, you can safely use either, but it’s good to recognize both when reading.
