What's the difference or which one is more idiomatic, if any?

  • I'm at home all of the day.

  • I'm at home all the day.


1 Answer 1


Neither of your examples is idiomatic although both are perfectly understandable and would hardly raise an eyebrow in conversation.

The most common expression would be I am at home all day. (Equally, all morning/afternoon.)

Of your two, the former is more likely although you will hear the expression all the day long, often in a poetic or lyrical context.

  • So it's better to say "I am at home all day because of quarantine"? Commented Jun 3, 2020 at 9:29

    @JudiciousAllure "I'm stuck home all day" is perhaps more fitting considering the circumstances. N.B no article in front of "day" unlike in your version.

  • You can use the expression 'all the day', but not about the day that has not finished yet. This phrase bears a strong idiomatic meaning of 'all that day' in the modern usage and refers in practice to some day that was in the past. That is why the sentence * 'I am at home all the day.' can be percieved as ungrammatical in the modern usage.

    @kngram: We still include the article in all the livelong day, but that's effectively a "frozen form", not reflective of more general usage today. Commented Jun 7, 2020 at 13:53
